everything the same from repo, but no interactive slide

[mkhalegh]

Dear Ramnath,

First, let me thank you for all the efforts you have put to maintain such great tools in Rstudio. I am becoming a big fan of slidify as I am passing "Developing Data Products" course on coursera.

However, I am running the exact example of interactive Interactive Chart with Controls from this repo. I did everything according to the descriptions. But, I can't see any interactive chart. I would be very thankful if you could give me some insight in this issue. I am struggling with interactive slides for a month and no luck in resolving it. I read all about interactive slides on forums and from your slidify website. But none helped me resolve these issues. I am now trying to reproduce the results from your repo. But,..

I get this error:

r Error in if (input[[paste0("runCode", i)]] != 0) return(isolate({ : argument is of length zero

my session info is:

Interactive Chart with Controls

library(slidify)
library(slidifyLibraries)
require(shiny)
require(rCharts)
slidifyUI(
 sidebarPanel(
 selectInput('sex', 'Choose Sex', c('Male', 'Female')),
 selectInput('type', 'Choose Type',
 c('multiBarChart', 'multiBarHorizontalChart')
 )
 ),
 mainPanel(
 tags$div(id = 'nvd3plot', class='shiny-html-output nvd3 rChart')
 )
)

And here is my app1.R:

require(rCharts)
output$nvd3plot <- renderChart({
 haireye = as.data.frame(HairEyeColor)
 n1 <- nPlot(Freq ~ Hair, group = 'Eye', type = input$type,
 data = subset(haireye, Sex == input$sex)
 )
 n1$set(dom = 'nvd3plot', width = 600)
 n1
})

@mkhalegh There have been so many changes in shiny and rmarkdown since I built this demo, that I am not surprised that it doesn't work any more. I will take a look at this to see if there is an easy fix. Thanks for bringing it to my attention.

@ramnathv Thanks for taking this into your attention. I look forward to your suggestions.

Hi Ramnath,

Thanks a lot for such a great package.

I am also facing the same issue, not able to see interactive plots. Everything else working fine. Could you please guide me to resolve this.

Thank you,
Naveen.
