Dear all,
I'm trying to use the GRASS function "r.mapcalc" using R package
"spgrass6", but I've got some trouble with it, I'm not even able to
parse this function:
> library(rgdal)
Le chargement a n?cessit? le package : sp

> parseGRASS("r.mapcalc")
Error : syntax error, unexpected '-', expecting NAME or STRING
Parse error does not seem to be XML, nor to identify a file name
Erreur dans parseGRASS("r.mapcalc") : r.mapcalc not parsed
I tried to change the XML encoding by
> setXMLencoding("latin1")
without success.
For example,
> parseGRASS("g.region")
is correctly running, I've got the description of the function.
Otherwise, my calculus with "r.mapcalc" within GRASS 6.4.0 is correctly
running.

Am I missing something? Any idea?
Thank you very much for your help and patience.
