Dear GRASS-community,

I have a very strange problem. I created a script in R (2.10.1) for the preparation of my datasets which work fine on my laptop (winxp). I use the "spgrass6" package and GRASS 6.4.1. As the script would run for days on my old laptop I now got a remote desktop connection to a much faster computer at the university (win7). However, while cmds like r.reclass or r.in.gdal work on that computer the r.patch cmd produces following error:

execGRASS("r.patch", flags=c("z"), parameters=list(input="mangroves_1989_138_044_LR_recl,mangroves_1989_138_045_UL_recl,mangroves_1989_138_045_UR_recl", output="testomat"), intern=T)

Error in system(cmd0, intern = TRUE) :
Createprocess konnte 'C:\GRASS6~1.1\bin\RPATCH~1.EXE --interface-description' nicht ausführen
Fehler in parseGRASS(cmd) : r.patch not found

I checked the GRASS directory and it is set right in the initGRASS command.

I hope you can help me with one. I have no clue what to do!

Thanks in advance,

Tim
