DESCRIPTION

WARNING: This module is superseded and will be removed in future versions of GRASS. Use the much faster r.univar instead.

r.univar calculates univariate statistics of a raster map. This includes the number of cells counted, mininum and maximum cell values, range, arithmetic mean, variance, standard deviation and coefficient of variation. Checking the 'extended statistics' box adds median, 1st and 3rd quartiles, and 90th percentile.
