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? Ciao Vittorio

I have a Mac OS X system. To deal with a long monthly electricity demand time-series I use the procedures TRAMO/SEATS with the MS-windows only Demetra programme and X12 under R resorting to the awkward - as far as the output is concerned - x12 R package running the relating Fortran code. I wonder if someone out there has attempted to translate TRAMO/SEATS and X12 into R native language? Ciao
