Dear R-Help, I need to convert a set of '.pdf' files into an equivalent set of '.txt' files. This is so that i can do some text mining on the content.
In the latest R-News letter (http://cran.r-project.org/doc/Rnews/ Rnews_2008-2.pdf), the package 'tm' for text mining is mentioned. In that lovely package, there is a function called 'readPDF()'. In order to use this, ?readPDF says "Note that this PDF reader needs both the tools pdftotext and pdfinfo installed and accessable on your system." These tools are available from http://www.foolabs.com/xpdf/download.html I am able to download this and use it easily from a dos window to convert a pdf file into a txt file. Question: how do i make these tools available to R, so that i can use the readPDF() function? Thank you in advance for any help, and I hope the above made sense.
