added a g.message about the temporary file:

v.class.mlR --verbose segments_map=lsat7_segs_stats training_map=training
train_class_colum=class processes=3
temporary file: D:\grassdata\nc_spm_08_grass7\user1\.tmp/unknown\10300.3.csv

AFAIR R in windows needs slashes, e.g.

> getwd()
[1] "C:/Users/myuser/Documents"
