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.
