#2594: r.univar output error
---------------------------------------+------------------------------------
Reporter: richardc | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.1
Component: Raster | Version: svn-releasebranch70
Keywords: r.univar statistics zones | Platform: Linux
Cpu: x86-32 |
---------------------------------------+------------------------------------
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
