[R-sig-Geo] Cluster identification using space-time permutations

[Virgilio Gómez-Rubio]

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.

Best,

Virgilio
