[R] Reading a web page in pdf format

[Vittorio]

Each day the daily balance in the following link

http://www.
snamretegas.it/italiano/business/gas/bilancio/pdf/bilancio.pdf

is 
updated.

I would like to set up an R procedure to be run daily in a 
server able to read the figures in a couple of lines only 
("Industriale" and "Termoelettrico", towards the end of the balance) 
and put the data in a table.

Is that possible? If yes, what R-packages 
should I use?

Ciao
Vittorio
