Hi,
Is there a (good) reason why there are no (or better: wrong) percentages in case of negative basemap values?
Here some sampe results:
basemap covermap percentage
-70 -7 inf
-70 63 inf
-50 -7 inf
-50 45 inf
As far as I can see this is the relevant line in r.statistics/o_distrib.c:
68 if (catb != basecat && basecat > 0)
I also created http://trac.osgeo.org/grass/ticket/763, some days ago.
