pca3D

R-CMD-check

pca3D creates 3D-style PCA scatter plots with ggplot2 from a prcomp object, including static views (plot_pca3d()) and rotating GIF animations of a full 360 degree spin (animate_pca3d()). Points can be coloured by metadata columns, any three PC dimensions can be selected, and variance explained can be annotated automatically.

Installation

You can install the development version of pca3D from GitHub with:

# install.packages("pak")pak::pak("pascalnoser/pca3D")

Example

A static view with plot_pca3d():

library(pca3D)
pca<- prcomp(iris[, 1:4], scale.=TRUE)
plot_pca3d(pca, metadata=iris, color_by=Species, axes="gizmo")

And a full rotating GIF with animate_pca3d():

animate_pca3d(
pca,
metadata=iris,
color_by=Species,
axes="gizmo",
file="man/figures/README-pca3d.gif"
)

For more on customising colours, axes, viewing angle, and dimension choice, see vignette("pca3D") or the function documentation (?plot_pca3d, ?animate_pca3d).
