[R] Extracting a a chunk of text from a pdf file

[Victor]

In an R script I need to extract some  figures from  many web pages in pdf format. As an example see http://www.terna.it/LinkClick.aspx?fileticket=TTQuOPUf%2fs0%3d&tabid=435&mid=3072 from which I would like to extract the "Totale: 1,025,823").
Is there any solution?
