[GRASS-user] Running GRASS within R (Rstudio) on MacOS

[Rainer Krug]

Hi

The problem is the gisBase. it is the directory with the e.g. lib, bin directories. I am not using the GRASS App but installed from Home-brew, so I can’t help you there. Just look for general intro on how to use Grass in R on Mac.

Cheers,

Rainer

I followed the instructions stated in the wiki (https://grasswiki.osgeo.org/wiki/R_statistics/rgrass7 <https://grasswiki.osgeo.org/wiki/R_statistics/rgrass7>), however some of the commands were not working for me. For instance, "grass70 --config path" (also with grass73 etc) does not work here, however I found the path to the application which is: /Applications/GRASS-7.3.app; i.e. using "open /Applications/GRASS-7.3.app" opens my grass installation.
