Hello, everyone:

I am looking the function of r.neighbors function, and I searched grass6.3 reference manual r.* commands. I did not found it.

Would anyone please tell me where I can find this command and how to perform Focal Cell neighbourhood analysis?

Thanks

be careful with r.mfilter - it rounds result to nearest integer (for historical reasons). If you work on floating raster and want to have floating output ... multipy map before filtering
