Description
There appears to be an error in the output of r.univar when -g and -t options are NOT used. It looks like a formatting error, where there is a mismatch between categories reported in r.univar and the actual category in the zone file. E.g. category 2 reported by r.univar is derived from category 1 of the zones file.
Example of output with -g and -t options:
r.univar -g -t map=cahpa_i0apr_05216_nc_remapped_nc_1@prcp05216ijk zones=BMR_bndry_epsg4326_rasterized@prcp05216ijk zone|label|non_null_cells|null_cells|min|max|range|mean|mean_of_abs|stddev|variance|coeff_var|sum|sum_abs 1|Category 1|2|0|3.58209799742326e-05|6.23035812168382e-05|2.64826012426056e-05|4.90622805955354e-05|4.90622805955354e-05|1.32413006213028e-05|1.75332042143714e-10|26.9887589010849|9.81245611910708e-05|9.81245611910708e-05 2|Category 2|1|0|3.53023679053877e-05|3.53023679053877e-05|0|3.53023679053877e-05|3.53023679053877e-05|0|0|0|3.53023679053877e-05|3.53023679053877e-05 3|Category 3|2|0|5.02148177474737e-05|8.14341983641498e-05|3.12193806166761e-05|6.58245080558117e-05|6.58245080558117e-05|1.5609690308338e-05|2.43662431522222e-10|23.7141009775611|0.000131649016111623|0.000131649016111623 4|Category 4|3|0|4.46328085672576e-05|8.2188387750648e-05|3.75555791833904e-05|6.12175620820684e-05|6.12175620820684e-05|1.56425403660131e-05|2.4468906910235e-10|25.552373916888|0.000183652686246205|0.000183652686246205 5|Category 5|3|0|3.81464305974077e-05|6.24195599812083e-05|2.42731293838006e-05|4.99398726484893e-05|4.99398726484893e-05|9.92133734132678e-06|9.8432934640405e-11|19.8665651615892|0.000149819617945468|0.000149819617945468 6|Category 6|2|0|1.89598704309901e-05|7.74326545069925e-05|5.84727840760024e-05|4.81962624689913e-05|4.81962624689913e-05|2.92363920380012e-05|8.54766619399701e-10|60.6611188093919|9.63925249379827e-05|9.63925249379827e-05
