Thanks Sotiri,

once again, delivery deadlines approaching, and I froze it.  I was playing for 
a while with conversions like the one you propose ( ...indeed, found many 
relevant posts).

Note, doing it in a pure TIFF (that would likely loose its spatial reference 
metadata) would require an additional step outside of R/GRASS to get the SRS 
attached back in an identical, regarding the spatial resolution and extent, 
TIFF. So as to get an GeoTIFF (again).

Thus,  I would prefer playing inside GRASS -> R -> GRASS only.

Thank you, Nikos
