2015-07-26 Thread Simone Ruzza
Dear list, apologies for the total beginner's question. I would like to use gwr.gauss function to calculate weights "manually" without resorting to ggwr.sel. I have seen the example from the spgwr manual: plot(seq(-10,10,0.1), gwr.Gauss(seq(-10,10,0.1)^2, 3.5), type="l") I was wondering if any

Dear list, apologies for the total beginner's question. I was wondering whether there is some function to compute the Moran's correlogram (e.g. sp.correlogram) for spatio-temporal data? thanks in advance, Simone ___ R-sig-Geo mailing list R-sig-Geo@r-
