Create a new RasterLayer where all cells that are NA in mask are set to NA, and that has the same values as x in the other cells.
Usage
mask(x, mask, ...)
Arguments
x
A RasterLayer object
mask
A RasterLayer object
...
Additional arguments. See below, under Methods
Value
A new RasterLayer object, and in some cases the side effect of a new file on disk.
Methods
A full call to the mask method for a RasterLayer is:
mask(x, mask, filename='', ... )rll{
x a RasterLayer object
mask a RasterLayer object
filename character. output filename
... Additional arguments, see Details
}
Details
If no filename is specified, and the resulting RasterLayer is too large to hold in memory, it is saved to a temporary file.
The following additional arguments can be passed, to replace default values for this function
rll{
format Character. Output file type. See writeRasterdatatype Character. Output data type. See dataTypeoverwrite Logical. If TRUE, "filename" will be overwritten if it exists
