Hello R Users,

I wanted to find the weights and adjacency matrix of texas that can be used in Openbugs.

library("spdep")
library("maps")
library("maptools")

tx_shape<-readShapePoly(".....\\Districts_10_11.shp")
tx_nb<-poly2nb(tx_shape)


There is a command called "dnearneigh" in spdep but is not useful here as it requires a set of coordinates for the whole data, but tx_shape is giving me coordinates for every district. 


I don't know what thing I am missing here. I would be glad if anyone can help with this.

Shant.
