[Qgis-user] R: Re: Join spreadsheet and Style "graduate"

[labiancamarilena at libero.it]

Thanks for the clarification, infact I also tried to convert the spreadsheet 
to csv or dbf but nothing. 
Yet the values ​​are numeric data (number of factories). 
How do I get to read these data as numbers and not as strings?
Thanks for any help.
