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

[Carlos Grohmann-2]

Hello all

I was laying around with R packages to do some rose plots. I've found
some, but none gives me what I really want (maybe because they were
made by climatologists and I am a geologist?)

What I want? 2 kinds of rose plots. One where the size of the petals
is proporcional to the frequency (number) of lineaments in a given
direction. Some packages do this, including heR.Misc
(http://www.exposurescience.org). So far, we're good.

Now the second kind of rose plot. In this one, the size of the petal
is proporcional to the accumulated length of the lineaments in that
direction.

The length attribute I get from GRASS, the azimuths, in R (from the
start_x, start_y, end_x, end_y GRASS gives me)

Now, how can I sort/sum the lengths based on the azimuth?

TIA

carlos

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

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...
