[GRASSLIST:1832] two categories in one raster-map?

[Dieter Lehmann]

Hi,
is it possible to refer to different
categorie-values in a single raster-map? (maybe stored in
a database with the database-interface) I want to do a
mapcalc expression somehow like:

r.mapcalc test = 'if(raster==1 and raster$tabelinfo2 == 3,1,0)'

Thanks,
Dieter
