Dear Lawrence, You might take a look at the scatter3d function in the Rcmdr package, which uses the rgl package. scatter3d() includes some smoothing, but not by ksmooth() or locpoly(), so you might have to alter it for your purposes, but that shouldn't be hard.
I hope that this helps, John -------------------------------- John Fox Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604 http://socserv.mcmaster.ca/jfox -------------------------------- > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > lawrence Perepolkin > Sent: Wednesday, October 20, 2004 7:18 AM > To: [EMAIL PROTECTED] > Subject: [R] Plotting a 3D surface > > Hi > > Does R have a function or has someone written a function to > draw a 3d surface from a scatter plot of values using either > ksmooth or locpoly.
