Subject: [R-sig-Geo] Cluster identification using space-time
permutations
Message-ID:
<aanlktikne0uycnywjiny34_xsq_kfyyt=zgmfnmhb...@mail.gmail.com>
Content-Type: text/plain
We've been using the SatScan space-time permutation scan statistic to
identify potential predation sites (ie clusters) from wolf GPS data. Are
there functions that I could use in R to run this cluster analysis?
Here's the reference:
Kulldorff et al. 2005 A SpaceTime Permutation Scan Statistic for Disease
Outbreak Detection
http://www.plosmedicine.org/article/info:doi/10.1371/journal.pmed.0020059
I've searched the RSiteSearch many times without luck. Any help would be
greatly appreciated!

Dear Jesse:
Rather than trying to rewrite the algorithm, you could call the executable
module of SaTScan from R, I think. There are 2 versions of SaTScan
available - one with a GUI interface and the other a callable executable.
See Kulldorff's web site www.satscan.org for downloads. There is a tech
support email address there also, in case you have trouble, but those
programmers don't know R.
Hope this helps.
