DESCRIPTION

37       WARNING: This module is superseded and will be removed in  future  ver‐
38       sions of GRASS.  Use the much faster r.univar instead.
39
40       r.univar  calculates  univariate  statistics  of  a  raster  map.  This
41       includes the number of cells counted, mininum and maximum cell  values,
42       range, arithmetic mean, variance, standard deviation and coefficient of
43       variation.  Checking the 'extended statistics' box adds median, 1st and
44       3rd quartiles, and 90th percentile.
