The latest code trace which I could find is this one:

GRASS GIS 5.5:
https://github.com/OSGeo/grass-legacy/tree/releasebranch_5_5/src/raster/r.binfer

I do not recall why the module has been abandoned in GRASS GIS 6
(maybe no particular reason and a volunteer could update it...?).

Another option might be to rely on R and use "rgrass7" to exchange
data between GRASS GIS and R.

Best,
Markus
