The previous post was in reference to MacOS. Can you check on your <br>
system that the Rscript executable is available from the GRASS command <br>
window? i.e.<br>
<br>
- start grass (even without the GUI)<br>
<br>
- go to the command shell<br>
<br>
- run Rscript -e "sessionInfo()"<br>
<br>
<br>
This will identify if the problem is due to missing PATH in the env <br>
variables.<br>
