[Qgis-user] R: Re: R: Re: Add table excel and categorize

[labiancamarilena at libero.it]

Hi,
thanks a lot.
I've solved the problem.
CSV is indeed recognized as a string but I downloaded Quantum 2.0 and with 
some tricks, the system allows to graduate values .
When I import CSV use " Custom delimiters " in this way successfully it loads 
the file.
Thank you very much!
