Rusers:
I am trying to compute a Moran's I coefficient for census tracts for
Indianapolis in R. I have a shapefile for Indianapolis and uploaded it
into R. I understand how to compute a Moran's I coefficient using knn2nb
command. How can I compute a Moran's I based on a edge/border contiguity

library(gstat)
demo(gstat3D)
It doesn't use the sp classes, and in the next version it will be like this:

n <- 50
