Re: [R-sig-Geo] Wavelet analysis of anisotropy in point patterns

2017-07-19 Thread Marcelino de la Cruz Rot 

Hi Domenico,

AFAIK, you should build your own functions to get the same analysis 
provided by the PASSaGE software. If you have some elementary R 
programming skills, following the description of the analysis proposed 
by Rosenberg(2004) shouldn't be much complicated. Otherwise...I don't know.


Good luck!

Marcelino

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
