⚠️There's a newer version (1.0-20) of this package.Take me there.

sf (version 0.7-2)

Simple Features for R

Description

Support for simple features, a standardized way to encode spatial vector data. Binds to 'GDAL' for reading and writing data, to 'GEOS' for geometrical operations, and to 'PROJ' for projection conversions and datum transformations.
