Spatial Ananlysis: zero.policy=TRUE doesn't work for no neighbour regions??
...ng to create a
Spatial Weights Matrix.
*I us the following code to create the Neighbourslist:*
>library(maptools)
>library(spdep)
>library(rgdal)
>location_County<- readShapePoly("....")
>proj4string(location_County)<- CRS("+proj=longlat ellps=WGS84")
>location_nbq<- poly2nb(location_County)
>summary(location_nbq)
*And get this Output:*

Number of regions: 3109
