Dear R-users,

I haven't found a way in the searchable archive to overplot a contour
(lines) over a surface.
I have a (n,m)  matrix that represents sea surface temperature that I
have plotted using image.plot(), filled.contour() or image(). I would
like to overplot this image with some contour lines of mixed layer depth
values(same size matrix). How can I do this?

 Any help is appreciated, thank you,

   Emmanuel
