The new pdftools package allows for extracting text and metadata from pdf files in R.

From the extracted plain-text one could find articles discussing a particular drug or species name, without having to rely on publishers providing metadata, or pay-walled search engines.

The main motivation behind developing pdftools was that Rpoppler depends on glib, which does not work well on Mac and Windows.

The pdftools package uses the poppler c interface together with Rcpp, which results in a lighter and more portable implementation.

The most important function is pdftext which returns a character vector of length equal to the number of pages in the pdf.

The pdftoc function shows the table of contents, i.e.

The poppler library provides all functionality to implement a complete PDF reader, including graphical display of the content.

In R we can use pdfrenderpage to render a page of the PDF into a bitmap, which can be stored as e.g.

Unfortunately the pdf format is pretty dumb and does not have notion of a table (unlike for example HTML).

But the output is still very dependent on the formatting of the original pdf table, which makes it very difficult to write a generic table extractor.

But with a little creativity you might be able to parse the table data from the text output of a given paper.
