I need transform the matrix
wdat
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 0 1 0 1 1 0
[2,] 1 0 0 1 1 0
[3,] 0 0 0 0 1 1
[4,] 1 1 0 0 1 0
[5,] 1 1 1 1 0 0
[6,] 0 0 1 0 0 0
to gal object. 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
