Dear R users,
Thank Dr. Divand for creating spdep, and thank everyone for your attention.
I attach a 30*30 matrix, which consists of 0 and 1. The matrix is a
"txt" file. I would like to change this matrix into a ".listw" file
so that I can estimate spatial auto-correlation. As a new user, I have
difficulties in using "read.fwf" and "mat2listw". Below are my
errors.
data1= read.fwf("30_30.txt", widths=1)
coords <- coordinates(data1)
col005 <- dnearneigh(points, 0, 1, attr(col.gal.nb, row.names = IDs))
summary(col005)
col005.w.mat <- nb2mat(col005, zero.policy=TRUE)
col005.w.b <- mat2listw(col005.w.mat)
......
Thank you
Zz
