Thank you for your advice, I send an e-mail to a french grass list.
That is no use. Use grass-stats if you need help with the R-GRASS interface, the developers do not read other channels regularly.
The best solution seems for me to work with future version
Work with forthcoming (soon to be stable) GRASS 7, not with the development version.
But I cannot install spgrass 7 or spgrass on windows 7 in R version 3.1.2 :
So download: http://download.r-forge.r-project.org/bin/windows/contrib/latest/spgrass7_0.1-0.zip and install from local zip file (untried). None of the developers uses Windows, so this isn't a priority. Alternatively, install R-tools foe Windows and then install the source package.
I am in the process of setting up a virtual machine (Windows 7, R, GRASS) to test it out (If I manage to deal with windows ...). Cheers, Rainer

There is ongoing discussion on the grass-stats list: http://lists.osgeo.org/mailman/listinfo/grass-stats The GRASS 7.0 RC1 is where many parameter names have been changed. The changes are quite large, so the current R spgrass6 package will only handle GRASS 6 up to GRASS 7.0 beta, while the new spgrass7 (in the spgrass project on R-Forge) is being matched to changes in GRASS 7.0 RC*. See: install.packages("spgrass7", repos="http://R-Forge.R-project.org") This is thanks to input and work by Rainer Krug and Markus Neteler. RC2 should be out soon too. spgrass6 will shift to maintenance mode only shortly after GRASS 7.0 is released, but will stay available. The parameter name changes are on: http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures#Optionschanges We have not checked against GRASS trunk. I think that your adaptation might match the regular 7.* series rather than the development trunk, but I agree with Rich that it would be worth asking on the GRASS users or developers list. Roger
Ask on the GRASS mail list; you can sign up at
If there are syntactic differences I would assume that those
in the > 7.1svn
are the future. I've used GRASS (on linux) since 4.0 and current
use > 7.1svn
so I've seen many differences over the past couple of decades.
