Hello, 

can you please explain me the steps to do it?I can't understand where I can
require the extraction..

Moreover I need to change the order of the entries ( by alphabetical order
for the NUTS 2  name) as I have to add a column with the cluster name (from
the analysis I am doing) in order to succeed -finally- at creating a map of
nuts 2 with different colors for each cluster of regions.

I am grateful for you kind attention, 

Valentina.
