Hi,

after starting R --vanilla within grass 6.4.1 on Debian amd64 squeeze, I get the following error message when calling

library (spgrass6)

Loading required package: spgrass6
Error : .onLoad failed in loadNamespace() for 'spgrass6', details:
call: read.dcf(gisrc)
error: Line starting 't ...' is malformed!

The error message is clear, your .gisrc file is malformed. I suggest running in R before library(spgrass6):

gisrc <- Sys.getenv("GISRC")
gisrc

to discover its name, and then examining the contents with, for example,

file.show(gisrc)

inside R. The keys and values should be arranged in the format described in ?read.dcf. Mine in a spearfish session is:

GISDBASE: /home/rsb/topics/grassdata
LOCATION_NAME: spearfish60
MAPSET: rsb
MONITOR: x0
GRASS_GUI: wxpython

for example. It may be that something has overwritten your gisrc file, so you may need to correct it. Within GRASS before starting R you can check it by saying:

cat $GISRC

Also look for any stale gisrc* files that may be being copied across when GRASS starts.

Hope this helps,

Roger

I'm running the up-to-date versions of spgrass6, sp, etc. with proj4 and gdal libraries from Debian. R version is 2.13.0. Any pointers on how to resolve this would be much appreciated. Cheers,

Martin
