Re: [R] Rcmdr and scatter3d
Dear Ted, I assumed that since Naiara was using scatter3d(), he wants a 3D dynamic scatterplot. He could add points (actually, spheres) to the rgl graph produced by scatter3d() -- the analog of plot() followed by points() for a 2D graph -- but doing so would be much more work than plotting by groups.

I'd like to use scatter3d (which is in R commander) to plot
more than one dataset in the same graph, each dataset with a
different color. The kind of stuff you would do with holdon

I read a recent message that was posted to this list with a

someone give me one example? How do you plot subgroups using
scatter3d?
Thanks a lot!
