⚠️There's a newer version (0.6-4) of this package.Take me there.

rgeos (version 0.3-26)

Interface to Geometry Engine - Open Source ('GEOS')

Description

Interface to Geometry Engine - Open Source ('GEOS') using the C 'API' for topology operations on geometries. The 'GEOS' library is external to the package, and, when installing the package from source, must be correctly installed first. Windows and Mac Intel OS X binaries are provided on 'CRAN'.
