Problem dissolving solution

[darribas]

I can't dissolve the shapefile for a solution, am I missing anything? I'm posting here an example using a toy example data (from pysal), but I have not been able to get it to work with other datasets too.

import pysal as ps
import clusterpy as clp
col = clp.importArcData(ps.examples.get_path('columbus'))
col.cluster('azpRTabu', ['HOVAL', 'CRIME'], 2, dissolve=1)

Which prints out the following output:

Dear Dani, I just tried the following code and it worked:

import clusterpy col = clusterpy.importArcData("clusterpy/data_examples/columbus") col.exportArcData("testOutput/columbus") col.cluster('azpRTabu', ['HOVAL', 'CRIME'], 2, dissolve=1) col.results[0].exportArcData("testOutput/ColDiss")
