I want to use some GRASS-GIS tools in R and I am using the rgrass package to interface R to GRASS GIS installed on my windows machine. When I run initGRASS(gisBase = "C:/Program Files/GRASS GIS 8.2", home = tempdir()) to initialize the environment, I get a warning with the message;

Warning message:
In system(syscmd, intern = intern, ignore.stderr = ignore.stderr,  :
  running command 'g.proj.exe -w' had status 1

I am using GRASS GIS version 8.2. I have installed PROJ version 9.2 separately and set the PROJ_DATA environment variable to the value of C:\OSGeo4W\share\proj. I am running out of options now. What could be the cause of this?

I have consulted these threads here and here but they refer to the older rgrass7 package which is now broken. Documentation to the newer rgrass package seems sparse.

  • With the help of `@rsbivand ` (Roger Bivand), the root cause of this problem has been narrowed down to the difference between the `proj.db` database used by current version of `terra` and `WinGRASS 8.2`. I am trying now to downgrade my installed `terra` to see how it goes. – Faustin Gashakamba Jun 01 '23 at 17:29
