allancameron / pdfr Goto Github PK

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?

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.

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.

I am using the latest release of R Studio on a Surface Pro 7. Windows 10.

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:

• Remove existing NAMESPACE file to replace with NAMESPACE generated by roxygen2
• Add httr and grDevices to Imports and move Rcpp11 to Suggests
• Add package level documentation to handle imports from ggplot2, Rcpp, and httr
• Add package level metadata with codemetar::write_codemeta()
• Update function documentation to import from grid and grDevices
• Re-formated the DESCRIPTION with use_tidy_description() (and added URLs + Authors)
• Update license with use_mit_license()
• Added a utils.R file to add a call utils::globalVariables()
• Replace the markdown README with a Rmd file
• Exported the testfiles data with use_data()
• Disabled execution of a broken test in test-pdrf.R
• Disabled execution of a broken example for 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.
