Hello list,
while exporting vector maps form GRASS to R using readVECT6(spgrass6),
null values in attributes become zeroes in R, and makes them
undistinguishable from real zero-valued attributes.
I'm making a work-around, by previously replacing zeroes by 0.5 in GRASS
(wich is an impossible value) and then reverting once in R.
But i wonder if there is a correct way of doing this that i didn't find.
If not, i suggest to add the feature of passing null values to NAs and
viceversa.
