%description
An interface between the 'GRASS' geographical information system ('GIS')
and 'R', based on starting 'R' from within the 'GRASS' 'GIS' environment,
or running a free-standing 'R' session in a temporary 'GRASS' location;
the package provides facilities for using all 'GRASS' commands from the
'R' command line. The original interface package for 'GRASS 5' (2000-2010)
is described in Bivand (2000) <doi: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-present). The 'rgrass' package modernizes the
interface for 'GRASS 8' while still permitting the use of 'GRASS 7'.
