persp and lines()
The help file for persp (in R 1.8.1, at least) includes a function
to "Add to existing persp plot". Have you tried that? Alternative,
have you considered "wireframe" in package lattice?
hope this helps. spencer graves

R-sters: I'm interested in keeping data plotted in persp to preserve the wireframe look, I'd just like to change one of the lines drawn (in either the x or y direction) into a different color so that it stands out. Or is there some way to add a line (say, via lines(), or abline()) to a persp() plot at the designated x or y that would follow the z surface contour? I could add a line using 2D representations of the data, but I'd like to use the perspective plot if possible. Any advice? Cheers, Jeff
