[R] 3d scatterplots of more than 1 data set

[John Fox]

Dear Saurav,

The scatter3d() function in the Rcmdr package will plot by groups, using
different colours for the groups. The function can be used directly or
called via the Rcmdr menus. scatter3d() appears to do what you want, but in
any event is a straightforward function, and you should be able to alter it,
or simply add to the plot using, e.g., rgl.spheres() from the rgl package.

I hope this helps,
 John
