Thank you very much Rolf,
an enlightening example for me! To my example: the 3D array should be
interpreted as a regular point pattern just as a reproducible example
(number of points = 11*11*11 / 1. coordinate = 0,0,0.1 / 2. coordinate =
0,0,0.2 etc.). The second point has the same structure
Paul,
Have you seen the new update of sphet(Ver1.4)? there is the command spreg
that allow you to use instruments for endogenous variables.

Hi R-Sig-Geo community!
I was recently trying to run ADEHabitat ecological niche factor analysis
(ENFA) using R in Linux. I did not get very far and would like some
assistance on how to make it work in the future.
I did the following commands:
I installed both ade4 and ADEHabitat on to R in
Dear Alannie,
I'm surprised that you have any difference from Windows to Linux, apart of
the memory problem... This said, you should consider switching to the new
version of adehabitat: adehabitatHS [1], which uses sp classes instead of
the old kasc. I wouldn't be too surprised if your
Dear Michela,
In addition to Alexandre answer, it is not advised to use the ENFA to
produce suitability maps. You might be interested in the MADIFA instead,
also available in adehabitatHS. See [1].
As for your scatter plot, you should investigate your variables
individually, e.g. with
bSomething interesting with pqR: I was working through the ASDAR book in
Chapter 2. In the accompanying code, one of the chunks said, this takes a
long time. I timed it with R-3.0.1 and got 17.28 elapsed time. In pqR, it
only took 8.513 in elapsed time.
Not too shabby!
Thanks,

Hi!
I am searching for a spatial package that will let me do spatial queries
between polygons (if they overlay, if they are at a certain distance). Can
anyone point me to a R package that will let me do this type of operations?
Many thanks.
