[R-sig-Geo] rgrass7 to be removed by Oct 2023, consider moving to rgrass instead

[Roger Bivand]

Dear GRASS and R users,

[ the text below was contributed by Roger Bivand and it is published online at: https://grass.osgeo.org/news/2023_06_05_retirement_of_rgrass7/ ]

The R package rgrass7 interfacing R and GRASS GIS will be removed from active availability on the Comprehensive R Archive Network (CRAN) during October 2023; it will be archived on CRAN. This is because the successor rgrass package has been available since mid-2022, and because the rgdal package on which rgrass7 depends for exchanging files between R and GRASS GIS will also be archived in October 2023, as described in R-spatial evolution project [0] reports [1].

The main change between rgrass7 and rgrass is that terra is used in place of rgdal for file transfer between R and GRASS. rgrass7 functions have been marked asdeprecated for almost a year now, and maintainers of packages using rgrass7 have been notified. Please also refer to https://rsbivand.github.io/foss4g_2022/modernizing_220822.html for more details.
