### 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.

### Installation

This package depends on GRASS version 8 or above.

If you use OSGeo4W on Windows (recommended), remember that you must start RStudio, Rgui or console R from within the OSGeo4W shell.

See the workshop on rgrass at FOSS4G 2022 for a detailed introduction with reproducible examples.
