[R] superposing lattice plots

I am sorry if this has already been asked but I can't find it. I want
to superpose two lattice plots, namely a levelplot and a contourplot
of two different variables with the same x-y scale. I found
information about panel.superpose but it does not seem to correspond
to what I want (I have two different variables, not groups of the
How can I do this? Is there a way to concatenate the two trellis
objects and plot that?
Simple example using simulated data:
I would like both plots to appear superposed.
PS: accessory question, for the enthusiast ;). When data in contained
in a matrix and x-y coordinates in separate vectors, as above, is
there a way to get level/contourplot to use x and y as the
coordinates vectors other than by "unrolling" the matrix in a
x y mat
1 1 0.125
1 2 0.1367
1 3 0.2345
and using mat ~ x*y ?
Thank you in advance. Sincerely,
