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

raster (version 2.2-31)

raster: Geographic data analysis and modeling

Description

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