Hi there,
Turns out it was a simply 'par' problem
I just needed to establish par(new = TRUE) after the first 'persp' plot
and prior to coding the 2nd 'persp' plot.
Thanks for your suggestions.

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).
If the surfaces are non-intersecting, you might be able to use
'wireframe' from the lattice package. See the second example
in ?wireframe.
