I had a look into the sources; I can't find a line of code where winGRASS
changes %HOME% at the moment; but it obvious uses %USERPROFILE% as %HOME%.
maybe just found it:
for trunk
https://trac.osgeo.org/grass/browser/grass/trunk/lib/init/grass.py#L712
712 def ensure_home():
713 """Set HOME if not set on MS Windows"""
714 if windows and not os.getenv('HOME'):
715 os.environ['HOME'] = os.path.join(os.getenv('HOMEDRIVE'),
716 os.getenv('HOMEPATH'))
and for the 7.0.x-line
https://trac.osgeo.org/grass/browser/grass/branches/releasebranch_7_0/lib/init/grass.py#L1338
1338 # set HOME
1339 if windows and not os.getenv('HOME'):
1340 os.environ['HOME'] = os.path.join(os.getenv('HOMEDRIVE'),
1341 os.getenv('HOMEPATH'))
OK, so the extension would be to look in %HOME%/Documents to see if there
is %HOME%/Documents/R, and if so do what? If R_LIBS_USER is set, do
nothing, if not, set R_USER, or guess which win-library is the relevant
one and set R_LIBS_USER? Even if this is redundant for non-R users?
