⚠️There's a newer version (2.1-4) of this package.Take me there.

sp (version 2.1-1)

Classes and Methods for Spatial Data

Description

Classes and methods for spatial data; the classes document where the spatial location information resides, for 2D or 3D data. Utility functions are provided, e.g. for plotting data as maps, spatial selection, as well as methods for retrieving coordinates, for subsetting, print, summary, etc. From this version, 'rgdal', 'maptools', and 'rgeos' are no longer used at all, see for details.
