I am trying to follow the tutorial here before I create some 3D scatterplots of my own.
# library library(rgl) options(rgl.printRglwidget = TRUE) # This is to output a rgl plot in a rmarkdown document. Note that you must add webgl=TRUE, results='hide' in the chunck header library(knitr) knit_hooks$set(webgl = hook_webgl) # Data: the iris data is provided by R data <- iris # Add a new column with color mycolors <- c('royalblue1', 'darkcyan', 'oldlace') data$color <- mycolors[ as.numeric(data$Species) ] # Plot par(mar=c(0,0,0,0)) plot3d( x=data$`Sepal.Length`, y=data$`Sepal.Width`, z=data$`Petal.Length`, col = data$color, type = 's', radius = .1, xlab="Sepal Length", ylab="Sepal Width", zlab="Petal Length") writeWebGL( filename="3dscatter.html" , width=600, height=600)
However, after doing this, 2 things seem to happen. First, I get these warnings:
Warning messages: 1: In snapshot3d(scene = x, width = width, height = height) : webshot = TRUE requires the webshot2 package; using rgl.snapshot() instead 2: In rgl.snapshot(filename, fmt, top) : this build of rgl does not support snapshots
I do not know what it means by
snapshot since that is not in my code. The second thing is after I run, a file named
