Hi. I have a shapefile. I guess because of cartography problem, the border of some of the units that are supposed to be physically connected are 'snapped' properly. As a result, when I use poly2nb, there are empty links.
I know I can set zero.policy=T in nb2listw. But I'm trying to use skater() function. I notice that it won't accept spatial weight matrix with empty link.
Any advice on how can I easily fix the matrix? Is there a way I can fill in empty link with nearest neighbors?
I'd really appreciate advice on how to manually tweak the connectivity matrix.
Thanks in advance!
K.
