⚠️There's a newer version (3.6-32) of this package.Take me there.

raster (version 1.9-5)

Geographic analysis and modeling with raster data

Description

Reading, writing, manipulating, analyzing and modeling of gridded spatial data. The package implements basic and high-level functions, as well as map algebra. Processing of very large files is supported.
