e most simple way is above. Personally, I use R to make the final maps
only when I have to produce a long series of simple maps.
I think the best way is the integration of GIS software with R, each one
with his specialty.

Hi!
As suggested, I'm using poly2nb to make queen and rook contiguity matrices,
but all they are first order. How can I work with another orders?

Hi!
Can I create queen or rook spatial weights with R?
I'm migrating from Geoda to R, is there any good introductory text for basic
functions of spatial econometrics with R ?
Best regards,

The best way to export the results to a shapefile is:
writePolyShape(res.adpt$SDF, "nameshape")
Is not?

Hi,
I'm using a SpatialPolygonsDataFrame object called "x" derived from a

Here is what I have:
