[GRASS-stats] counting/sorting lineament lenght according to their azimuth in R

[jarekj at amu.edu.pl]

Yes, to your second problem try to use combination on table() and cut()
function, unfortunatly I cannot send you sample of my code where I use 
to the same problem because I'm far from my computer.. (
btw: it is far from your question but for that problem I rather used
readVECT6() and than lm() on imported vector structure instead start and
end x y from grass. It gives better results on irregular or curved
lineament.. the sample code is somewhere on the list...
