[GRASS-user] Rscript error when using v.class.mlR

[Jamille Haarloo]

I am using standalone winGRASS, but installed it with OSGeo4W because I
also use QGIS.
I was using version 8.2.1, but went back to 7.8.5 and OSGeo4W v1.
With R4.3.1 getting other errors, and with R4.0 there was also trouble
finding the R script? (FileNotFoundError: [WinError 2] The system cannot
find the file specified.)
I checked the input text files. These don't have NA values.
I am doing a test classification with limited training-data.
