<p>What you need to try is:</p>

<p><font size="5" face="monospace">Rscript -e "sessionInfo()"</font></p>
<p><br>
</p>
<p>The GRASS module <font face="monospace">v.class.mlR</font>
needs to be able to "find" the Rscript executable in order to run.</p>

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>
