What operator in mapcalc should I use to evaluate a mode from a given window: r.mapcalc "test_andmode = mode (map1[-1,-1] && map1[-1,0] && map1[-1,1] && map1[0,-1] && \ map1[1,-1] && map1[1,1] && map1[0,0] && map1[0,1] && map1[-1,0] && map2[-1,-1] && map2[-1,0] && \ map2[-1,1] && map2[0,-1] && map2[1,-1] && map2[1,1] && map2[0,0] && map2[0,1] && map2[-1,0])"
Is the && correct to list values?
