Cluster identification using space-time permutations
Dear Jesse, You can look at the functions in the DCluster package for the (purely) spatial scan statistic. You could start from there. I have also some other code for spatio-temporal clustering that I have not yet released (and I believe that the permutation algorithm may not be tuned) but I will be happy to share it with you.

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 Space?Time 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! Jesse Whittington Wildlife Biologist Banff National Park [[alternative HTML version deleted]]
