[R] Character from Symbol Font on rgl Plot

[Tom La Bone]

I want to print characters from the symbol font (or perhaps even Wingdings)
in an rgl 3d plot, but I am having no luck. So, what do I have to do in
order to get this snippet to print out a character from the symbol font?

library(rgl)
open3d()
text3d(1,1,1,"a",adj=c(0.5,0.5),cex=10,family="symbol",font=1)

I am on Windows XP with R 2.9.1.

Tom
