[R] response surface

[Nathan Leon Pace, MD, MStat]

I have a response surface model (z ~ x*y) which is displayed as a 
trellis wireframe plot.

I wish to cut the surface at various linear planes in the z axis (e.g. z 
= 50, etc.). Are there any packages which offer functions to do so?

Thanks,

Nathan
