[Qgis-developer] R Sextante error

Agustin

2 quick things:

1) I am going to prepare a document with instructions to use the
latest version from git. That might help you and others as well.

2)If you are doing a presentation about SEXTANTE, that puts you in my
list of "privileged" users :-) That means that you can (and you
should) ask me for direct help or to prepared a tailored version so
you have it ready for your presentation.

Anyway, do you have any deadline for that?. I am presenting SEXTANTE
at the Russian FOSS4G conference in mid november, and I should have a
new version ready by that time. In the meantime, as I said, and if you
do not manage to use git, I can send you just a zip file with changes
that affect the R engine in SEXTANTE, so you can just unzip them in
you QGis plugins folder and test them.

Regards

Victor
