⚠️There's a newer version (3.6-31) of this package.Take me there.

raster (version 3.6-3)

Geographic Data Analysis and Modeling

Description

Reading, writing, manipulating, analyzing and modeling of spatial data. The package implements basic and high-level functions for raster data and for vector data operations such as intersections. This package has been superseded by the "terra" package .
