R help - Mar 2013 - Creating 3d partial dependence plots

Help,

I've been having a difficult time trying to create 3d partial dependence
plots using "rgl".  It looks like this question has been asked a
couple
times, but I'm unable to find a clear answer googling.  I've tried
creating
x, y, and z variables by extracting them from the partialPlot output to no
avail.  I've seen these plots used several times in articles, and I think
they would help me a great deal looking at interactions.  Could someone
provide a coding example using randomForest and rgl?  It would be greatly
appreciated.

Thank you,
Jerrod Parker

I think you are making your question too hard to answer.  Show us an 
example of what you tried (a "self-contained, minimal example", of 
course) and we'll suggest ways to fix it.

It needs to be done "by hand", in that partialPlot() does not handle
more than one variable at a time.  You need to modify its code to do that (and
be ready to wait even longer, as it can be slow).
