Does the contourplot() routine have an argument analogous to the
"levels" argument in the contour() routine? More generally, is there a
way for the user to fix the contour levels in contourplot()?  Thanks.

Assuming lattice:

Also assuming lattice, cuts would be the analog of nlevels=<n> in contour, but to specify particular levels which I believe was the request, it appears one would need to set pretty=FALSE and use the at= parameter in panel.contourplot.
