Installing PDFtotext in R

I am trying to run the PDFtotext package in R.

PDFtotext

When I run these commands:

library(tm) pdf=readPDF(control=list(text="-layout"))(elem=list(uri=uri), language="en", id="idi")

I get this error:

Error in system2("pdftotext", c(control$text, shQuote(x), "-"), stdout = TRUE) : "pdftotext" not found

In addition: Warning message: running command "pdfinfo" "C:*****NCLR AR 2005.pdf" had status 127

Does anyone know what the problem might be?

Sys.which("pdftotext") is ""? I.e. the file is not found. Have you installed it? You may want to try the package pdftools as an alternative to read pdfs.

Sys.which("pdftotext")

""

pdftools

This function of the tm library requires that pdftotext and pdfinfo are installed on your computer. You can download precombiled binaries for the most common operating systems here. These programs are not installed in or by R, as the title of your question suggests. They need to be installed as separate programs on your system.

In widows add the binary to your path. System-->Advanced -->Environment Variables -->add the directory containing the pdftotext.exe
