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

raster (version 3.5-2)

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. See the manual and tutorials on to get started.
