This post shows how to build a 3d scatterplot and make it spin thanks to the
rgl package. Reproducible code is provided.
rgl package is the best option to build 3d charts in R. Please see this post for an introduction to 3d scatterplots using it.
It also provides the
play3d() functions that allow to animate the 3d chart, and eventually to export the result at a
.gif format. Here is an application to the famous
iris dataset, with a nice animated 3d scatterplot chart.
library( rgl ) library(magick) # Let's use the iris dataset # iris # This is ugly colors <- c("royalblue1", "darkcyan", "oldlace") iris$color <- colors[ as.numeric( as.factor(iris$Species) ) ] # Static chart plot3d( iris[,1], iris[,2], iris[,3], col = iris$color, type = "s", radius = .2 ) # We can indicate the axis and the rotation velocity play3d( spin3d( axis = c(0, 0, 1), rpm = 20), duration = 10 ) # Save like gif movie3d( movie="3dAnimatedScatterplot", spin3d( axis = c(0, 0, 1), rpm = 7), duration = 10, dir = "~/Desktop", type = "gif", clean = TRUE )
