Yes, the description on:
http://cran.r-project.org/web/packages/spgrass6/index.html
uses "6+" to signal that subsequent versions are intended to work. Since
the package only uses system(), it will work as long as
--interface-description returns an XML file. Plenty of examples and
scripts stop working because GRASS 6 and 7 modules have different flags
and/or parameter names, but in principle only for that reason. It's hard
for me to check - it would be useful to have a translation table for flag
and parameter names by module where changes have occurred.
Best wishes,
Roger
