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.

  Ask on the GRASS mail list; you can sign up at

http://grass.osgeo.org/.

 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.
