I don't understand this. How do you install standalone winGRASS with OSGeo4W? But that's another question.
Jürgen re-packaged now winGRASS 8.3.0 in OSGeo4W version 2 including the Rbatch-files.
have a look at https://github.com/ggrothendieck/batchfiles/blob/master/R.bat#L520 and following code lines.
the relevant one is https://github.com/ggrothendieck/batchfiles/blob/master/R.bat#L532
"echo path - Add R_TOOLS, R_MIKTEX ^& R_PATH to path for this cmd line session (0)"
just tried here in OSGeo4W version 2 with re-packaged winGRASS 8.3.0:
* starting a GRASS session
* typing into the windows console: R path => this adds temporarily the path to R to %PATH%
* typing into the windows console: RScript -e "sessionInfo()" => outputs all necessary infos if R is correctly found (as Micha suggested)
when temporarily the path to R is added to %PATH% within the winGRASS session, try v.class.mlR.
Kind regards
Helmut
