 ### Interface Between GRASS Geographical Information System and R
 
-Interpreted interface between GRASS geographical information system and R, based on starting R from within the GRASS GIS environment, or running free-standing R in a temporary or existing GRASS location; the package provides facilities for using all GRASS commands from the R command line, see <https://rsbivand.github.io/rgrass/articles/use.html>.

 The original interface **GRASS** package for `GRASS 5` (2000-2010) is described in Bivand (2000) (https://doi.org/10.1016/S0098-3004(00)00057-1) and Bivand (2001) (https://www.r-project.org/conferences/DSC-2001/Proceedings/Bivand.pdf). This was succeeded by **spgrass6** for `GRASS 6` (2006-2016) and **rgrass7** for `GRASS 7` (2015-2023). The **rgrass** package modernizes the interface for `GRASS 8` while still permitting the use of `GRASS 7`.
