Hi Paulo,
you may want to take a look at

http://cran.r-project.org/web/views/Spatial.html

there, you can find all "spatial" packages that 
can be useful for your question.
There is also a  a mailing list R-sig-geo that where 
you can ask all those kind of question.

Hope that this helps.

Cheers

Anna

Oggetto: [R]  Spatial Autocorrelation


Hello, 

I have a matrix with the distances among sites. And I have another matrix
with the presence and absence of  each species in each site. I would like to
test the spatial autocorrelation among sites.

I have tried to use the function gearymoran of the ade4 package, but error
messages keep popping up. Do you know any function for me to test the
spatial autocorrelation of my data?

Thanks,

Paulo Branco
