Questions tagged [r-sf]

The motivation behind the `sf` package is to provide a complete, standardized implementation of simple features in R, with links to GDAL, GEOS and Proj.4. There is a also https://gis.stackexchange.com/ for spatial R questions.

sf is a new R package for handling and analyzing spatial data in R. While various R packages are available that provide classes and methods for spatial data (e.g. sp, rgdal and rgeos), sf, which is developed by Edzer Pebesma and others, is intended to gradually replace the well known sp package.
