Hi everyone,
When using the extension "v.class.mlR" I get an error [Message 1] (see
below) that "Rscript" cannot be located. I traced this back to the
script for "v.class.mlR" and edited line 908 to read the direct path
to Rscript - '/usr/local/bin/Rscript' rather than 'Rscript' alone.
However, when I re-open GRASS 8.0 I get an error [Message 2] that the
extension failed when loading and that the operation isn't permitted.
I allowed for the application to have administrative rights but it
still doesn't work. Does anyone know how to work around this or solve
the issue finding "Rscript"?
I have R running and have installed necessary packages. I'm
running GRASS on MacOS Monterey.
This looks like a Mac problem (which I know nothing about).
To test, can you run, first from a terminal:
micha@RMS:~$ Rscript -e "sessionInfo()"
Now run the same from within a GRASS session:
(here's what I get)
micha@RMS:QGIS$ g.version
GRASS 8.1.dev (2022)
micha@RMS:QGIS$ Rscript -e "sessionInfo()"

If the Rscript executable is not found, then v.class.mlR cannot be run.
Any help would be appreciated.
