How I do with spdep?RSiteSearch("matrix listw") gets you to several threads on the R-sig-geo list, suggesting in your case: w <- mat2listw(wdat) # convert matrix to spatial weights list write.nb.gal(w$neighbours, "wdat.gal") # write neighbours component of spatial weights list as GAL file Roger Bivand> > Thanks in advance for the help. > > Bernardo. > University of Concepci?. > > ______________________________________________ > R-help <at> r-project.org mailing list > stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > >
