I would tend to agree. BTW, meanwhile I changed in r71022 default
method from 'mean' (module was calculating mean value of categories)
to 'n' (number of points in cell). I also added new parameters
`column` and `method`. Later I will update examples.

Does r71023 correspond to what you are after ?

Before it gave expected result for points with Z, e.g. in full NC loc:

r.vect.stats in=elev_lid792_bepts out=ground

Now it gives error (likely due to column=options['column']), but more
importantly, other binning modules (r.in.lidar, r.in.xyz) have mean as
default, so we need to be careful not to be inconsistent and produce
expected results. Can this have no default? Or perhaps the "use" paradigm
as with other modules such as v.to.rast is appropriate here
(use=attr|cat|z), then again we have the issue of default value versus no
value for default, but at least it is general enough to accommodate both
XYZ point clouds and points with attributes.

right, it needs to be fixed (checking if input is 2D or 3D).

Mean value of cats if input is 2D is misleading in any case.

Would make sense to me. Thanks for staring this module. I was
surprised that such tool did not exists in GRASS. Martin

I have tested r.vect.stats (with pipe) and compared it with pipe in shell -
the time is the same (expected behavior). Here is the test with pipe in
shell for 19693050 (almost 20 million) points:

time sh -c "v.out.ascii input=points layer=-1 format=point sep=pipe |
r.in.xyz input=- output=bin2 method=mean sep=pipe --o"
real1m5.982s
user1m39.120s
sys0m1.740s

And here is the same test but using temporary file (similar result with and
without SSD):

time sh -c "v.out.ascii input=points layer=-1 format=point sep=pipe
output=tmp.txt --o; r.in.xyz input=tmp.txt output=bin3 method=mean sep=pipe
--o"
real1m32.933s
user1m30.472s
sys0m1.796s

According to this, using temporary file requires 1.4 more time.

I have now create one with the openNRW LiDAR data and published the
