It should, right?
What I would expect to see is just the contour plot, since that should overwrite the map() plot. Once you get filled.contour() working, try adding the map using: map('worldHires',xlim=c(-10,40),ylim=c(35,70),boundary = TRUE, border=0.1, add = TRUE) You may have to put the xlim= and ylim= into the filled.contour() call to get what you want.
