R help - Feb 2006 - Saving surface3d Output

Hello,

Please could someone advise if it's possible to save the graphical output
from the surface3d() function? I have tried the dev.copy() function to
save as a pdf but an error message says I cannot copy from the null
device.

Are you talking about surface3d in the rgl package?  It doesn't use the 
standard R graphics system, so dev.copy() won't help.  You need 
rgl.snapshot, which can create png files.  You'll need some other 
utility to convert those to pdf.
