[GRASS-user] Using output from r.statistics

since the calculated statistics are stored as labels in the output map, you
have to use the @ operator in the mapcalc formula in order to access the
labels instead of the clump categories, in your case.

Subject: [GRASS-user] Using output from r.statistics
I have used r.statistics to calculate the sum of a cover map based on a
base map. When I use the Query tool I get these:
The first two corresponds to Geographic Location the third Base map
clump ID and the last one it corresponds to the value of the sum
When I try to use this output, in mapcalc, it does not use the values
obtained in r.statistics but the clump value Which does not make much
sense. How can I use the r.average valeus of this raster?
