Dear R users;

Is there any way to intersect a filled contour image and a polygon? My
problem is that I want to create a kriging map and the boundaries of
my map are given by the coordinates of the polygon.

So far I can superompose the polygon in the filled.contour image but I
don't know how to get rid of the contour image outside of the polygon

Any hint will be appreciated
