What are you doing with the plot?  If including in a document, it is
should be easy to include them as two subfigures (it is LaTeX).  If you
want to do this on one on-screen device it isn't actually that hard: use
print.trellis() to put the wireframe() one where you want it, and use
par(fin) to select a figure region and call contour() within that.  I've
done that sort of thing several times when I wanted overlapping figure
regions, usually because wireframe() gave too large margins.
