R scripts to tweak PDF files

R scripts to tweak pdf

This repo contains some R scripts that I use to tweak PDF files.

Environment

• R
• R package: knitr and tinytex
• LaTeX compiler (MikTeX, TeX Live or TinyTeX. tinytex::install_tinytex() can install it for you, if needed)

How

• Copy your PDF files into input folder
• Run the R script
• Find the output PDF files in output folder

Script

• add-head-to-pdf.R: Add a customized header (the file name) to the PDF files
• add-head-to-pdf-with-some-landscape.Rnw: Rnw file that allows you to add header to landscape PDF files.
• multiple-pdfs-to-one.R: Merge multiple PDF files to one using Ghostscript.
