My question is in regard to the spdep and GeoDa packages. Do you know how
to extract a neighborhood/adjacency matrix from R? I need a matrix that has
all the neighborhoods on the X and Y axis, and then a r=1 when the
neighborhoods touch, and a r=0 when neighborhoods don't touch. I
think the Moran's I functions use a matrix like this when they estimate
Moran's I. I can estimate Moran's I, but I can't figure out how to
extract the matrix. I've been trying to do this for months and I
just can't get it.
Thank you so much. The R project is an invaluable gift to the scientific
and statistical community.
