[GRASS-dev] r.sum in SVN?

GRASS GRASS developer

Hello list,

I am looking for summing up all pixels of a raster into one value
(output to stdin).
r.sum was supposed to do it earlier. However, it does not appear in SVN...

Could anyone help me locating it, it may have been absorbed into another module.

Thank you,
Yann

It is a regular module:

GRASS 6.4.0svn (eu_laea):~ > r.sum --help

Description:
Sums up the raster cell values.

Hope this helps,

As suggested in:

I have removed r.sum, r.average and r.median, as equivalent
functionality is available via r.statistics{,2,3}.

Will update the wiki page.

apparently it was removed in trunk, see r34408, r34438
"Remove r.sum, r.average, r.median - redundant due to r.statistics{,2,3}"

try `r.univar -g`
