[GRASS-stats] [Fwd: Re: [R-sig-Geo] Errror with gmeta6()]

[Agustin Lobo]

I've upgraded to qgis 1.2.0-2~jaunty1build1
and ligdal1-1.6.0-grass 1.6.0-3~jaunty1
and everything seems to work fine regarding the qgis grass link.

Regarding R - grass:
If I :
1. start qgis
2. start qgis grass plugin
3. open mapset
4.open maptools
5.open grass shell
6. start R
7. require(spgrass6)
8.gmeta6() works fine

but if I
5. open grass shell
5a. open en xterm &  (as I've always done, so that I keep an open grass 
console)
6 start R in the new xterm
7. require(spgrass6) works fine (and notifies the mapset)
8. gmeta6() does not work:
 > gmeta6()
g.region: error while loading shared libraries: libgrass_vect.so: cannot 
open shared object file: No such file or directory
Error in if (file.exists(file) == FALSE) if (!missing(asText) && asText 
==  :
  argument is of length zero
Error in parseGRASS(cmd) : g.region not parsed

It might be a different behavior of ubuntu jaunty at opening new xterm 
consoles?
