Blank certain areas of a contour plot
...filled.contour() and a call to map(). Everything is fine but I need to "blank" (in Golden Surfer nomenclature) the areas of my domain that lay over the sea, as I do not have observations there and structures are completely artificial. Is there any function out there that can use the mapsdata database to "blank" the sea areas of my plot? Otherwise, can anybody think of a shortcut to get a similar effect on the final map (not showing the interpolated precipitation areas over the sea? Thanks a lot in advance, V?ctor. -- ----------------------------------------------------...
