Clip a raster
Hi, with the raster package you could use: polygons to raster (?polygonsToRaster), converting the Costa Rica shapefile to a raster and then use mask (?mask). Best Johannes

?Dear list members,
I download bioclim data in a raster format (estension: .bil) and I would
like to clip the variables to a ploygon stored as a shapefile (Costa
Rica outline).
How can I do that?
I read the raster file like this:
x <- readGDAL("bio1_23.bil")
Thank you very much in advance.
Best,
Manuel
