You get an incorrect result if the default PDF extraction engine is not found on your computer, see? tm:: readPDF. Those engines are not part of R or of the tm package, and it depends upon your computer system whether the necessary programs are already set up.

As soon as these programs are correctly set up, you must be able to draw out the text of the PDF file without a system call, by utilizing the readPDF() function of the tm plan.

As a quick fix I suggest that you copy the precompiled binary of pdfinfo in your working directory. You can show your working directory in an R session with getwd().
