Hello:

Apart from readPDF in the tm package, you can use the pdf to text converter command in linux, which is "pdftotext".  Say "file.pdf" is your file, from R you'd use:

system("pdftotext file.pdf -layout")

This invokes the pdftotext command from within R and creates a file called "file.txt" with the converted pdf, which you'd have to read into R.  The -layout option is so the conversion to text is as similar as possible to the original layout of the pdf file.
