Thanks a lot for your suggestion but... Can I do that using the/a land-sea information from the 'worldHires' database (from mapdata)? Best, VÃctor. Greg Snow wrote:
After you have interpolated your data, replace the values in the areas of the o cean with NA, then filled.contour will not plot in those areas.

Then, I plot and locate geographycally the resulting field with a 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, VÃctor. -- ----------------------------------------------------------------------- VÃctor Homar Santaner Grup de Meteorologia Edif.
