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

[Carlos "Guâno" Grohmann]

Thanks Jarek, but CircStats only gives me my first need (petals =
frequency of lineaments). the length of the petals can be adjusted by
a _constant_ value, not ny the accumulated length.

tks

Carlos
