Not a mapcalc expert, but what about turning your lookup table in a true
raster, I mean create a 3colsx7rows LUT raster with values from your
table, then use this "map" in an r.mapcalc expression, calling LUT[i,j]
to retrieve the value corresponding to ageClass i and dc j
Sorry to interfere if my proposition is stupid ;-)
