Thank you Marcelino,
I already had a look at those functions and, although they do the job,
I was wondering how to analyze anisotropy in point pattern using
wavelet analysis.
I tried to use the WaveletComp package, but with no success. It looks
to me that packages for wavelet analysis work fine with temporal data,
but I couldn't find the way to use it with spatial point patterns.
How could I get in R the same analysis provided by the PASSaGE software?
Thank you!

Hi Domenico,
In spatstat you have several functions to detect anysotropy in point
patterns:
- the sector K-function, Ksector();
- the pair orientation distribution, pairorient();
- the anisotropic pair correlation function, Kmeasure().
See the help pages of these functios or, even better, consult pages

Hi all,
I'm running wavelet analysis of anisotropy in point patterns using
the PASSaGE software by Rosenberg et al.

I wonder how I can do the same analysis using R.
Thanks,
Dome
