Hi,

I am making barplots . I am using the default shape of barplots with a pipe
but I wants to build bars in various 3d shapes. I have install rgl using
install.packages('rgl') for this purpose, but when I am doing library(rgl),
it shows

Error in library(rgl) : there is no package called 'rgl'

What are the other ways to build such plots of variuos shapes.

Is that *TeachingDemos *replace it..I am not sure how to use it for such
task.

Thanks in advance
Jeet
