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

Hi,

I try to run GRASS73 within R (actually R-studio) using the rgrass7 library on MacOS 10.12.6. I followed the instructions stated in the wiki (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.

So I tried to initialize GRASS (North Carolina location - PERMANENT) from within R using the initGRASS() command:

initGRASS(gisBase = “/Applications/GRASS-7.3.app”, home = tempdir(),
gisDbase = “/Users/Johannes_Radinger/Documents/GRASS-GIS/”,
location = “nc_spm_08_grass7”, mapset = “PERMANENT”, SG=“elevation”,
override=TRUE)

However I get following error(s):

sh: g.gisenv: command not found
sh: g.gisenv: command not found
sh: g.gisenv: command not found
sh: g.gisenv: command not found
sh: g.gisenv: command not found
sh: g.version: command not found
Error in system(paste(“g.version”, get(“addEXE”, envir = .GRASS_CACHE), :
error in running command

So what I am doing wrong? Do I miss some arguments in my command or is this related to my Mac environment? Any suggestion I should try to solve that problem?

Thanks and best regards,
Johannes

Hi Rainer,

I used following commands and got following errors and output (using Rstudio). I also included now the output from sessionInfo() after loading “rgrass7”:

Hi

How did you run these commands from R, which error did you get?

Could you provide a transcript of your errors?

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
