    + +

    This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

    +
    +

    Overview

    +

    The mapgl R package provides an interface to Mapbox GL JS and MapLibre GL JS for creating interactive maps in R. It is designed to feel familiar to R users while making the powerful capabilities of both mapping libraries available.

    +
    +
    +

    Common Development Commands

    +
    +

    Package Building and Installation

    +
    +# Build and install the package locally
+devtools::install()
+
+# Check the package for issues
+devtools::check()
+
+# Generate documentation from roxygen2 comments
+devtools::document()
+
+# Run tests
+devtools::test()
+
+# Build the package
+devtools::build()
    +
    +
    +

    Vignette and Documentation

    +

    +
    +

    Shiny Development

    +
    +# When developing Shiny apps with mapgl, use:
+shiny::runApp("app.R", reload = TRUE)
    +
    +
    +

    Testing Individual Functions

    +
    +# Load the development version
+devtools::load_all()
+
+# Test individual functions
+library(mapgl)
+map <- maplibre() |>
+  add_circle_layer(data = sf_object, ...)
    +
    +
    +
    +

    Architecture and Code Structure

    +
    +

    HTMLWidgets Architecture

    +

    The package uses the htmlwidgets framework to bridge R and JavaScript:

    +
    1. +R Functions (R/ directory): +
      • +mapboxgl.R / maplibre.R: Main widget creation functions
        • +
      • +layers.R: Functions for adding map layers (circles, fills, lines, etc.)
        • +
      • +sources.R: Functions for adding data sources
        • +
      • +controls.R: Functions for adding UI controls
        • +
      • +shiny.R: Shiny integration with proxy functions
        • +
      • +plugins.R: Integration with JS plugins (globe minimap, geocoder, etc.)
        • +
      2. +
    2. +JavaScript Bindings (inst/htmlwidgets/ directory): +
      • +mapboxgl.js / maplibregl.js: Main JS widget bindings
        • +
      • +mapboxgl_compare.js / maplibregl_compare.js: Compare view implementations
        • +
      • YAML files define dependencies for each widget
        • +
      3. +
    3. +External Libraries (inst/htmlwidgets/lib/ directory): +
      • MapLibre GL JS (vendored)
        • +
      • Mapbox GL JS (loaded from CDN)
        • +
      • Various plugins (globe-minimap, draw, geocoder, etc.)
        • +
      4. +
    +
    +

    Widget Communication Pattern

    +
    1. R functions create list structures with map instructions
      2. +
    2. These are serialized to JSON and sent to JavaScript
      3. +
    3. JavaScript interprets instructions and updates the map
      4. +
    4. Shiny proxy functions send messages to existing maps
      5. +
    +
    +

    Key Design Patterns

    +

    Layer Management: Each layer requires a source. The package automatically creates sources when needed:

    +
    +# This creates both a source and a layer
+add_circle_layer(map, id = "circles", source = "data", data = sf_object)
    +

    Proxy Pattern: For Shiny apps, proxy functions allow updating existing maps:

    +
    +maplibre_proxy("map_id") |>
+  set_filter("layer_id", list("==", "property", "value"))
    +

    Expression System: The package supports Mapbox GL expressions:

    +
    +interpolate(
+  column = "value",
+  values = c(0, 100),
+  colors = c("blue", "red")
+)
    +

    Control Positioning: Controls can be positioned at 8 locations: - “top-left”, “top-center”, “top-right” - “bottom-left”, “bottom-center”, “bottom-right” - “middle-left”, “middle-right”

    +
    +
    +

    Dependencies and Versions

    +
    • MapLibre GL JS: v5.3.0 (vendored)
      • +
    • Mapbox GL JS: v3.12.0 (CDN)
      • +
    • R dependencies: htmlwidgets, sf, geojsonsf, shiny, etc.
      • +
    +
    +

    Working with Styles

    +

    The package supports multiple style sources: - mapbox_style(): Official Mapbox styles (requires token) - maptiler_style(): MapTiler styles (requires API key) - carto_style(): CARTO styles (free) - Custom style URLs or JSON objects

    +
    +
    +

    Testing Changes

    +
    1. Test JavaScript changes by modifying files in inst/htmlwidgets/ +
      2. +
    2. Test R changes by running devtools::load_all() and testing interactively
      3. +
    3. Use the examples in vignettes/ as test cases
      4. +
    4. Test Shiny functionality with apps in vignettes/ or create minimal examples
      5. +
    +
    +

    Current Issues and Edge Cases

    +
    • Globe minimap positioning in MapLibre with “bottom-right” position has CSS issues
      • +
    • Compare views require special handling for synchronized map updates
      • +
    • Some Mapbox-specific features may not work in MapLibre and vice versa
      • +
    +
    +

    Specific instructions

    +
    • DO NOT create an examples folder
      • +
    • DO NOT create R script files or any other files within the folder before getting explicit approval
      • +
    • Code style should follow Posit’s Air formatter
      • +
    • Code style prefers snake case (with words separated by underscores) rather than camel case.

    Because of the way that side-by-side maps generated with the +compare() function work in mapgl, +comparison maps require their own rendering functions. For Mapbox maps, +you can use mapboxglCompareOutput(), +renderMapboxglCompare(); and +mapboxgl_compare_proxy(); for MapLibre, use +maplibreCompareOutput(); +renderMaplibreCompare(); and +maplibre_compare_proxy(). For compare proxies, you can +target the side of the map you want to modify with the argument +map_side = "before" (left or top) or +map_side = "after" (right or bottom).

In a story map, users typically scroll through a web page in +which different map views and elements of the “story” are shown as the +user scrolls down. The mapgl package brings story maps +in Shiny to R users, and supports both Mapbox and MapLibre backends as +well as Leaflet.

    +

    This tutorial will help you learn how to build a basic story map +Shiny app with mapgl. You’ll rely on the following three functions when +building your story:

    +
      +

    • story_map() sets up the user interface component for +your story map. You’ll wrap this in a Shiny layout function; it is +recommended to use fluidPage() (or +bslib::page_fluid()) which will get you a standard +full-screen story map template. story_map() defaults to +Mapbox maps; you can use story_maplibre() for MapLibre +maps, and story_leaflet() for Leaflet.

      • +

    • Within story_map(), you’ll define a named list of +sections to be passed to the sections parameter. You’ll use +the story_section() function to build each section. In +story_section(), you’ll specify a title (set +to NULL or "" to omit it) as well as content, +which will be a list of UI elements you want to put in your section +panel. This can be HTML elements (defined with tags$p(), +tags$a(), tags$img(), etc.) as well as Shiny +inputs or outputs.

      • +

    • Within your server function, you’ll then use the +on_section() function to bring your story map to life. +on_section() allows you to link Shiny events to specific +story sections. This means that you can trigger map movements, add data, +or even perform analyses on user scroll.

      • +
    +
    +

    Moving the map on scroll +

    +

    Let’s take a look at how this works with a basic example. We’ll build +a story map with two sections: an introductory section, and a second +section where the map “flies to” a location when the user scrolls.

    +

    To get started, let’s build a basic user interface without any map +actions. In ui, we set up story_map() inside a +fluid page with two sections. In server, we’ll create a +Mapbox globe with mapboxgl() and +renderMapboxgl(). In most cases you’ll want to set the +option scrollZoom = FALSE when you initialize your map so +map scrolling behavior doesn’t interfere with story scrolling.

    +
    +library(shiny)
+library(mapgl)
+
+ui <- fluidPage(
+  story_map(
+    map_id = "map",
+    sections = list(
+      "intro" = story_section(
+        "Introduction",
+        "This is a story map."
+      ),
+      "location" = story_section(
+        "Location",
+        "Check out this interesting location."
+      )
+    )
+  )
+)
+
+server <- function(input, output, session) {
+  output$map <- renderMapboxgl({
+    mapboxgl(scrollZoom = FALSE)
+  })
+}
+
+shinyApp(ui, server)
    +

    +

    You’ll note that scrolling will transition between story sections, +and that you can still interact with the map by clicking and panning. +However, because we haven’t set up any actions in server, +nothing else happens when you scroll between sections.

    +

    We can change this by using the on_section() function. +In on_section(), you’ll specify the map ID (in this case, +"map") and the section ID to link to an action; the section +ID is the name of the corresponding list element defined in the list +passed to sections in the UI. You’ll then define an +expression, much like you would in observeEvent() in Shiny, +to be executed when a given section appears.

    +
    +library(shiny)
+library(mapgl)
+
+ui <- fluidPage(
+  story_map(
+    map_id = "map",
+    sections = list(
+      "intro" = story_section(
+        "Introduction",
+        "This is a story map."
+      ),
+      "location" = story_section(
+        "Location",
+        "Check out this interesting location."
+      )
+    )
+  )
+)
+
+server <- function(input, output, session) {
+  output$map <- renderMapboxgl({
+    mapboxgl(scrollZoom = FALSE)
+  })
+  
+  on_section("map", "location", {
+    mapboxgl_proxy("map") |> 
+      fly_to(center = c(12.49257, 41.890233), 
+             zoom = 17.5,
+             pitch = 49,
+             bearing = 12.8)
+  })
+  
+}
+
+shinyApp(ui, server)
    +

    +

    The map zooms into the Colosseum in Rome on user scroll. If you +scroll back up to the top, however, you’ll notice that the view does not +return to the original globe. This can be remedied by tying an +on_section() event to the introductory section.

    +
    +library(shiny)
+library(mapgl)
+
+ui <- fluidPage(
+  story_map(
+    map_id = "map",
+    sections = list(
+      "intro" = story_section(
+        "Introduction",
+        "This is a story map."
+      ),
+      "location" = story_section(
+        "Location",
+        "Check out this interesting location."
+      )
+    )
+  )
+)
+
+server <- function(input, output, session) {
+  output$map <- renderMapboxgl({
+    mapboxgl(scrollZoom = FALSE)
+  })
+  
+  on_section("map", "intro", {
+    mapboxgl_proxy("map") |> 
+      fly_to(center = c(0, 0),
+             zoom = 0,
+             pitch = 0,
+             bearing = 0)
+  })
+  
+  on_section("map", "location", {
+    mapboxgl_proxy("map") |> 
+      fly_to(center = c(12.49257, 41.890233), 
+             zoom = 17.5,
+             pitch = 49,
+             bearing = 12.8)
+  })
+  
+}
+
+shinyApp(ui, server)
    +

    +

    For map transitions, in addition to fly_to(), you might +consider using ease_to() and jump_to() +depending on your use case. Map transition functions support camera +options and animation +options as keyword arguments when applicable.

    +
    +
    +

    Adding data and modifying story appearance +

    +

    In many cases, you’ll want to use story maps to visualize data that +you’ll add to a Mapbox / MapLibre basemap. Let’s build an example of how +a real estate firm might use a story map to market a property.

    +
    +library(shiny)
+library(mapgl)
+library(mapboxapi)
+
+property <- c(-97.71326, 30.402550)
+isochrone <- mb_isochrone(property, profile = "driving", time = 20)
+
+ui <- fluidPage(
+  tags$link(href = "https://fonts.googleapis.com/css2?family=Poppins:wght@300;400;600&display=swap", rel="stylesheet"),
+  story_map(
+    map_id = "map",
+    font_family = "Poppins",
+    sections = list(
+      "intro" = story_section(
+        title = "MULTIFAMILY INVESTMENT OPPORTUNITY",
+        content = list(
+          p("New Class A Apartments in Austin, Texas"),
+          img(src = "apartment.png", width = "300px")
+        ),
+        position = "center"
+      ),
+      "marker" = story_section(
+        title = "PROPERTY LOCATION",
+        content = list(
+          p("The property will be located in the thriving Domain district of north Austin, home to some of the city's best shopping, dining, and entertainment.")
+        )
+      ),
+      "isochrone" = story_section(
+        title = "AUSTIN AT YOUR FINGERTIPS",
+        content = list(
+          p("The property is within a 20-minute drive of downtown Austin, the University of Texas, and the city's major employers.")
+        )
+      )
+    )
+  )
+)
+
+server <- function(input, output, session) {
+  output$map <- renderMapboxgl({
+    mapboxgl(scrollZoom = FALSE,
+             center = c(-97.7301093, 30.288647),
+             zoom = 12)
+  })
+
+  on_section("map", "intro", {
+    mapboxgl_proxy("map") |>
+      clear_markers() |>
+      fly_to(center = c(-97.7301093, 30.288647),
+             zoom = 12,
+             pitch = 0,
+             bearing = 0)
+
+  })
+
+  on_section("map", "marker", {
+    mapboxgl_proxy("map") |>
+      clear_layer("isochrone") |>
+      add_markers(data = property, color = "#CC5500") |>
+      fly_to(center = property,
+             zoom = 16,
+             pitch = 45,
+             bearing = -90)
+  })
+
+  on_section("map", "isochrone", {
+    mapboxgl_proxy("map") |>
+      add_fill_layer(
+        id = "isochrone",
+        source = isochrone,
+        fill_color = "#CC5500",
+        fill_opacity = 0.5
+      ) |>
+      fit_bounds(
+        isochrone,
+        animate = TRUE,
+        duration = 8000,
+        pitch = 75
+      )
+  })
+
+}
+
+shinyApp(ui, server)
    +

    +

    Let’s break down some key elements of this story map.

    +
      +

    • We’re loading a Google font, “Poppins”, into our Shiny app with +tags$link(). This allows us to use Poppins as our font +globally in story_map() by passing it as an argument to +font_family. The appearance of panels can also be modified +section-by-section if you prefer.

      • +

    • In each story section panel, we are passing a list of HTML items +to content. The introductory section shows how to include a +local image (which should be in a www folder local to your +app); you can also reference remotely-hosted images or include all other +HTML elements supported by Shiny. Also note the +position = "center" argument to position the introductory +panel in the center of the screen; "left" is the default, +and "right" is also supported without the need for +additional CSS customization.

      • +

    • As in the first example, all of our story actions defined in +calls to on_section() operate on the Mapbox GL proxy +object, "map". In this example, we use +add_markers() to add a marker at a location, and +add_fill_layer() to add a 20-minute drivetime isochrone +created with the Mapbox API. Transitions between the views are handled +with fly_to() and fit_bounds(), and +clear_layer() and clear_markers() calls are +used to control which data layers are visible as the user goes forward +and backward through the story.

      • +
    +
    +
    +

    Integrating Shiny inputs and outputs +

    +

    While the story map feature in mapgl is built in a +unique way to accommodate map-based scrollytelling, it is still creating +an R Shiny app. This means that all of Shiny’s functionality and +interactivity is available to you as you build your story maps. The list +of items you pass to content in any given story section +panel can include both Shiny inputs as well as Shiny +outputs which can correspond to the content visible on your +story maps.

    +

    Let’s set up a scenario that adds interactivity to the data displayed +in the Fundamentals +of map design with mapgl vignette. We’ll make a map of median age in +Florida, which will display with the introductory story panel. The user +selects a county to display; on scroll, the story will then zoom to the +selected county and show a histogram of values for Census tracts in that +county.

    +
    +library(shiny)
+library(mapgl)
+library(tidycensus)
+library(tidyverse)
+library(sf)
+
+fl_age <- get_acs(
+  geography = "tract",
+  variables = "B01002_001",
+  state = "FL",
+  year = 2023,
+  geometry = TRUE
+) |>
+  separate_wider_delim(NAME, delim = "; ", names = c("tract", "county", "state")) %>%
+  st_sf()
+
+ui <- fluidPage(
+  story_maplibre(
+    map_id = "map",
+    sections = list(
+      "intro" = story_section(
+        "Median Age in Florida",
+        content = list(
+          selectInput(
+            "county",
+            "Select a county",
+            choices = sort(unique(fl_age$county))
+          ),
+          p("Scroll down to view the median age distribution in the selected county.")
+        )
+      ),
+      "county" = story_section(
+        title = NULL,
+        content = list(
+          uiOutput("county_text"),
+          plotOutput("county_plot")
+        )
+      )
+    )
+  )
+)
+
+server <- function(input, output, session) {
+
+  sel_county <- reactive({
+    filter(fl_age, county == input$county)
+  })
+
+  output$map <- renderMaplibre({
+    maplibre(
+      carto_style("positron"),
+      bounds = fl_age,
+      scrollZoom = FALSE
+    ) |>
+      add_fill_layer(
+        id = "fl_tracts",
+        source = fl_age,
+        fill_color = interpolate(
+          column = "estimate",
+          values = c(20, 80),
+          stops = c("lightblue", "darkblue"),
+          na_color = "lightgrey"
+        ),
+        fill_opacity = 0.5
+      ) |>
+      add_legend(
+        "Median age in Florida",
+        values = c(20, 80),
+        colors = c("lightblue", "darkblue"),
+        position = "bottom-right"
+      )
+  })
+
+  output$county_text <- renderUI({
+    h2(toupper(input$county))
+  })
+
+  output$county_plot <- renderPlot({
+    ggplot(sel_county(), aes(x = estimate)) +
+      geom_histogram(fill = "lightblue", color = "black", bins = 10) +
+      theme_minimal() +
+      labs(x = "Median Age", y = "")
+  })
+
+  on_section("map", "intro", {
+    maplibre_proxy("map") |>
+      set_filter("fl_tracts", NULL) |>
+      fit_bounds(fl_age, animate = TRUE)
+  })
+
+  on_section("map", "county", {
+    maplibre_proxy("map") |>
+      set_filter("fl_tracts", filter = list("==", "county", input$county)) |>
+      fit_bounds(sel_county(), animate = TRUE)
+  })
+
+}
+
+shinyApp(ui, server)
    +

    +

    Let’s walk through how this works.

    +
      +

    • The UI code will be familiar, though we are now using the +MapLibre backend with story_maplibre(). The main difference +is our inclusion of a Shiny selectInput() in the first +story panel and two Shiny outputs in the second story panel. As we’ve +set it up, users can select a county at the beginning of the story, and +then get a different output when they scroll down.

      • +

    • A reactive object sel_county() will be used to get +county-specific values for the second story panel, and will help us +determine the map’s extent as we want to zoom to the selected +county.

      • +

    • That said, we don’t use sel_county() directly on the +map. Instead, we use mapgl’s set_filter() function, which +is more performant than filtering data by clearing a layer and re-adding +it. This allows us to invoke the underlying setFilter() +JavaScript method (see +here for more documentation) and operate directly on the map layer +itself. Setting the filter to NULL clears the filter and +gives us back the entire state of Florida.

      • +

    • We note that the content of the second panel is entirely Shiny +outputs: an h2 header that corresponds to the selected county, and a +histogram of median age values for Census tracts in that county drawn +with ggplot2.

      • +
    +
    +
    +

    Sharing your stories / next steps +

    +

    As your story map is a Shiny app, you’ll need to publish it to a +Shiny server to share it. Posit’s ShinyApps.io and Connect Cloud products are nice +options if you don’t want to set up your own Shiny server.

    +

    If you are building story maps with mapgl, please let me know about +it! I’m also planning some trainings / workshops on this feature, so +please do reach out if you are interested.

    mapgl (development version)

    +
    • Enhanced draw control functionality with improved feature editing capabilities: +
      • Added ability to load existing features from map sources into the draw control for editing either when initializing the draw control or via add_features_to_draw() +
        • +
      • Fixed vertex styling to properly highlight selected vertices during editing
        • +
      • Extended draw control support to compare views, enabling feature editing in side-by-side map comparisons
        • +
      • Improved compatibility with both Mapbox GL JS and MapLibre GL JS
        • +
      • +
    • Fixed hover_options for vector tile sources in MapLibre (#67): +
      • Added proper source layer handling for vector tiles when using hover effects
        • +
      • Now works correctly with PMTiles and other vector tile sources that include feature IDs
        • +
      • Note: Vector tiles must include feature IDs for hover effects to work. GeoJSON sources automatically generate IDs.
        • +
      • +
    • Enhanced tooltip functionality with expression support: +
      • Tooltips can now use expressions for dynamic content generation
        • +
      • Use get_column() to reference feature properties in tooltips
        • +
      • Added concat() helper function for combining strings and expressions
        • +
      • Example: tooltip = concat("<strong>Name:</strong> ", get_column("name"), "<br>Value: ", get_column("value")) +
        • +
      • Works with both regular tooltips and set_tooltip() in Shiny applications
        • +
      • +
    +
    +

    mapgl 0.2.2

    CRAN release: 2025-05-23

    +
    • Added mapboxgl_view() and maplibre_view() functions for quick visualization of sf objects with automatic geometry detection and column-based styling (#102).
      • +
    • Added support for rain and snow effects on Mapbox GL maps with set_rain() and set_snow() functions.
      • +
    • Added add_globe_control() for MapLibre maps, allowing users to toggle between “mercator” and “globe” projections.
      • +
    • Fixed issue with set_style() in Shiny applications for both Mapbox and MapLibre maps (#99).
      • +
    • Fixed namespacing issue in get_drawn_features() for Shiny modules (#95).
      • +
    • Improved compare functionality with better control support and swiper color customization.
      • +
    +
    +

    mapgl 0.2.1

    CRAN release: 2025-03-18

    +
    • Improved styling and positioning behavior of the layers control. Users can now customize the appearance of the layers control, and the layers control is collapsed by default with cleaner appearance. Added ability to link legends to specific layers with the new layer_id parameter in add_legend(). When a layer is toggled in the layers control, its associated legend will automatically show or hide.
      • +
    • Added support for custom legend positioning with new margin parameters (margin_top, margin_right, margin_bottom, margin_left) that allow fine-grained control over legend placement.
      • +
    • Fixed layers control toggle button state to correctly reflect the initial visibility of layers, resolving the issue with layers set to visibility = "none" showing as active in the control.
      • +
    • Support for the compare() plugin in Shiny applications, with new rendering and proxy functions for comparison apps in Mapbox and MapLibre.
      • +
    • New mode parameter in compare() allowing users to choose between "swipe" mode with a comparison slider, and "sync" mode which displays synchronized maps side-by-side.
      • +
    • Updates throughout the codebase to allow features to be used in comparison maps via Shiny proxy sessions.
      • +
    +

    Value

    A comparison widget.

    +
    +

    Details

    + +
    +

    Comparison modes

    + + +

    The compare() function supports two modes:

    • mode="swipe" (default) - Creates a swipeable interface with a slider to reveal portions of each map

      • +

    • mode="sync" - Places the maps next to each other with synchronized navigation

      • +

    In both modes, navigation (panning, zooming, rotating, tilting) is synchronized between the maps.

    +
    + +
    +

    Using the compare widget in Shiny

    + + +

    The compare widget can be used in Shiny applications with the following functions:

    After creating a compare widget in a Shiny app, you can use the proxy functions to update either the "before" +(left/top) or "after" (right/bottom) map. The proxy objects work with all the regular map update functions like set_style(), +set_paint_property(), etc.

    +

    To get a proxy that targets a specific map in the comparison:

    +

    # Access the left/top map
+left_proxy <- maplibre_compare_proxy("compare_id", map_side = "before")
+
+# Access the right/bottom map
+right_proxy <- maplibre_compare_proxy("compare_id", map_side = "after")

    +

    The compare widget also provides Shiny input values for view state and clicks. For a compare widget with ID "mycompare", you'll have:

    • input$mycompare_before_view - View state (center, zoom, bearing, pitch) of the left/top map

      • +

    • input$mycompare_after_view - View state of the right/bottom map

      • +

    • input$mycompare_before_click - Click events on the left/top map

      • +

    • input$mycompare_after_click - Click events on the right/bottom map

      • +
    + +

In a story map, users typically scroll through a web page in which different map views and elements of the "story" are shown as the user scrolls down. The **mapgl** package brings story maps in Shiny to R users, and supports both Mapbox and MapLibre backends as well as Leaflet. + +This tutorial will help you learn how to build a basic story map Shiny app with mapgl. You'll rely on the following three functions when building your story: + +- `story_map()` sets up the user interface component for your story map. You'll wrap this in a Shiny layout function; it is recommended to use `fluidPage()` (or `bslib::page_fluid()`) which will get you a standard full-screen story map template. `story_map()` defaults to Mapbox maps; you can use `story_maplibre()` for MapLibre maps, and `story_leaflet()` for Leaflet. + +- Within `story_map()`, you'll define a named list of sections to be passed to the `sections` parameter. You'll use the `story_section()` function to build each section. In `story_section()`, you'll specify a `title` (set to NULL or `""` to omit it) as well as `content`, which will be a list of UI elements you want to put in your section panel. This can be HTML elements (defined with `tags$p()`, `tags$a()`, `tags$img()`, etc.) as well as Shiny inputs or outputs. + +- Within your `server` function, you'll then use the `on_section()` function to bring your story map to life. `on_section()` allows you to link Shiny events to specific story sections. This means that you can trigger map movements, add data, or even perform analyses on user scroll. + +## Moving the map on scroll + +Let's take a look at how this works with a basic example. We'll build a story map with two sections: an introductory section, and a second section where the map "flies to" a location when the user scrolls. + +To get started, let's build a basic user interface without any map actions. In `ui`, we set up `story_map()` inside a fluid page with two sections. In `server`, we'll create a Mapbox globe with `mapboxgl()` and `renderMapboxgl()`. In most cases you'll want to set the option `scrollZoom = FALSE` when you initialize your map so map scrolling behavior doesn't interfere with story scrolling. + +```{r, eval = FALSE} +library(shiny) +library(mapgl) + +ui <- fluidPage( + story_map( + map_id = "map", + sections = list( + "intro" = story_section( + "Introduction", + "This is a story map." + ), + "location" = story_section( + "Location", + "Check out this interesting location." + ) + ) + ) +) + +server <- function(input, output, session) { + output$map <- renderMapboxgl({ + mapboxgl(scrollZoom = FALSE) + }) +} + +shinyApp(ui, server) +``` + +![](images/story-1a.gif) + +You'll note that scrolling will transition between story sections, and that you can still interact with the map by clicking and panning. However, because we haven't set up any actions in `server`, nothing else happens when you scroll between sections. + +We can change this by using the `on_section()` function. In `on_section()`, you'll specify the map ID (in this case, `"map"`) and the section ID to link to an action; the section ID is the name of the corresponding list element defined in the list passed to `sections` in the UI. You'll then define an expression, much like you would in `observeEvent()` in Shiny, to be executed when a given section appears. + +```{r, eval = FALSE} +library(shiny) +library(mapgl) + +ui <- fluidPage( + story_map( + map_id = "map", + sections = list( + "intro" = story_section( + "Introduction", + "This is a story map." + ), + "location" = story_section( + "Location", + "Check out this interesting location." + ) + ) + ) +) + +server <- function(input, output, session) { + output$map <- renderMapboxgl({ + mapboxgl(scrollZoom = FALSE) + }) + + on_section("map", "location", { + mapboxgl_proxy("map") |> + fly_to(center = c(12.49257, 41.890233), + zoom = 17.5, + pitch = 49, + bearing = 12.8) + }) + +} + +shinyApp(ui, server) +``` + +![](images/story-1b.gif) + +The map zooms into the Colosseum in Rome on user scroll.

This allows us to use Poppins as our font globally in `story_map()` by passing it as an argument to `font_family`. The appearance of panels can also be modified section-by-section if you prefer. + +* In each story section panel, we are passing a list of HTML items to `content`. The introductory section shows how to include a local image (which should be in a `www` folder local to your app); you can also reference remotely-hosted images or include all other HTML elements supported by Shiny. Also note the `position = "center"` argument to position the introductory panel in the center of the screen; `"left"` is the default, and `"right"` is also supported without the need for additional CSS customization. + +* As in the first example, all of our story actions defined in calls to `on_section()` operate on the Mapbox GL proxy object, `"map"`. In this example, we use `add_markers()` to add a marker at a location, and `add_fill_layer()` to add a 20-minute drivetime isochrone created with the Mapbox API. Transitions between the views are handled with `fly_to()` and `fit_bounds()`, and `clear_layer()` and `clear_markers()` calls are used to control which data layers are visible as the user goes forward and backward through the story. + +## Integrating Shiny inputs and outputs + +While the story map feature in __mapgl__ is built in a unique way to accommodate map-based scrollytelling, it is still creating an R Shiny app. This means that all of Shiny's functionality and interactivity is available to you as you build your story maps. The list of items you pass to `content` in any given story section panel can include both Shiny _inputs_ as well as Shiny _outputs_ which can correspond to the content visible on your story maps. + +Let's set up a scenario that adds interactivity to the data displayed in the [Fundamentals of map design with mapgl](https://walker-data.com/mapgl/articles/map-design.html) vignette. We'll make a map of median age in Florida, which will display with the introductory story panel.

The main difference is our inclusion of a Shiny `selectInput()` in the first story panel and two Shiny outputs in the second story panel. As we've set it up, users can select a county at the beginning of the story, and then get a different output when they scroll down. + +* A reactive object `sel_county()` will be used to get county-specific values for the second story panel, and will help us determine the map's extent as we want to zoom to the selected county. + +* That said, we don't use `sel_county()` directly on the map. Instead, we use mapgl's `set_filter()` function, which is more performant than filtering data by clearing a layer and re-adding it. This allows us to invoke the underlying `setFilter()` JavaScript method ([see here for more documentation](https://maplibre.org/maplibre-gl-js/docs/API/classes/Map/#setfilter)) and operate directly on the map layer itself. Setting the filter to `NULL` clears the filter and gives us back the entire state of Florida. + +* We note that the content of the second panel is entirely Shiny outputs: an h2 header that corresponds to the selected county, and a histogram of median age values for Census tracts in that county drawn with ggplot2. + +## Sharing your stories / next steps + +As your story map is a Shiny app, you'll need to publish it to a Shiny server to share it. Posit's [ShinyApps.io](https://www.shinyapps.io/) and [Connect Cloud](https://connect.posit.cloud/) products are nice options if you don't want to set up your own Shiny server. + +If you are building story maps with mapgl, please let me know about it!
