An R package to extract text from pdf.
License: Other
Hello @AllanCameron! I really appreciate you creating this package – I'm using it to extract text from some older reports at work and reformat the text into a tabular structure. When I went to look-up the documentation for pdfpage()
I realized that exporting the documentation is one of the things that remained incomplete with the package.
I just forked the package and went ahead and made the following changes to get the documentation filled in and get the package to pass devtools::check()
without errors. Here are all the changes I made:
codemetar::write_codemeta()
use_tidy_description()
(and added URLs + Authors)use_mit_license()
utils::globalVariables()
use_data()
draw_glyph()
If this all looks good, I'm happy to open a pull request.
I also noticed that the size parameter in pdfgraphics()
may need to be changed to linewidth to work with the most recent version of ggplot2 (see this post for more information). I can test this out and add it to the same pull request or open a separate issue if you'd like to discuss.

Error: Couldn't open file.
I have been using pdftools with no issues. Just installed PDFR
Hi
I've just installed this package and tried to use pdfpage()
and pdfdoc()
to read in some text.
In both cases I immediately get the error
Error in .pdfdoc(pdf) : Couldn't find string in dictionary.
and no other output.
Can you help?
Need to convert the Unicode ligatures and digraphs to letter pairs
downloaded PDFR. Seems to be installed correctly. Tried pdfboxes ( "my.pdf", 1) received Error: Couldn't open file. Note that pdftools can read this file.
Some fonts have no encodings specified except in the font program (e.g. some book-form pdfs from Project Gutenburg). Although a chunk of the file program is binary, the header contains a text-form encoding map that may be used for ligatures etc.
