Hi,
I tried to install R packages required for the GRASS-R interface by
using the following command (copied from
http://www.geog.uni-hannover.de/grass/statsgrass/grass6_r_install.html):
/install.packages (c(sp, spgrass6,rgdal,maptools), dependencies
=TRUE)/
rgdal package was installed successfully;
There were problems to find 'sp' and 'maptools' packages. The error
message was /: dependencies 'sp' and 'maptools' are not available/.
I tried to download the packages from three different mirrors with the
same result ( http://cran.fr.r-project.org/ ,
http://cran.mirroring.de/, http://probability.ca/cran/ )
http://probability.ca/cran/
I then failed to download 'spgrass6' since it required to download first
sp
can anybody tell me what mistake I did and how (where?) I can get these
packages
The note in the OSGeo Journal:
http://www.osgeo.org/files/journal/final_pdfs/OSGeo_vol1_GRASS-R.pdf
is more recent, although the note you accessed is accurate, and says just:
install.packages(spgrass6, dependencies = TRUE)
should be enough, because all the packages are on CRAN, and current sp
and maptools are on at least http://cran.fr.r-project.org.
Topics like this are best raised on the R-sig-geo list, or perhaps on the
GRASS STATGRASS list. It is also good practice to say what platform you
are on (OS, R version, etc.) as reported by sessionInfo().
Thank you very much by advance
