Dear list,
Does anyone know how to make nb objects (to eventually make spatial
weights) with spdep using an attribute in a shapefile's data frame?
Consider, for example, all property parcels on the same street segment
should be defined as neighbors. In the parcel polygons I have the
associated street segment name.
KNN forces sparsely settled areas to become neighbors, which is undesirable
for the subsequent analyses.
Distances between parcels vary, so distance-based neighbors are also
undesirable in this case.
Contiguity-based methods do not connect parcels on opposite sites of the
same street segment.
Is there a way to use an attribute to define what constitutes a neighbor?
All ideas welcome,
Dexter
