Thanks, Romain. I've certainly used that to draw lines and points in the plots produced by 'persp'; however, my problem is that I need to incorporate an entirely new z function (not just a plane) onto the same plot (i.e., using the same x and y values).

Just look at the examples in ?persp.
There is a function called trans3d defined in it that will traduce your 3D
coordinates to 2D, and so you will be able to draw lines with lines function.
