[R] looking for 3D plotting with real-time rotation

[John Fox]

Dear Ben,

The scatter3d() function in the Rcmdr package uses rgl to plot
rotatable point clouds and regression surfaces. The function is usable
with or without the Rcmdr GUI. You'll find an illustrative plot at
<http://socserv.socsci.mcmaster.ca/jfox/Courses/S-course/index.html>.

I hope this helps,
 John
