I am making a set of slides using rmarkdown and the LaTeX option of outputting it to beamer.
I have two templates I use in my slides - one specific for the LaTeX options, and one pandoc template that I have modified to account for some additional feature of my slides.
I have defined an option in the YAML header called to_print which is a boolean TRUE/FALSE that I pass to the pandoc template that tells it to add a package and clean up the slides for printing.
I also want to use this variable to define the name of the files. The basic idea being that I want to have one .rmd file for my slides, and then just changing this one option to signify that it's for printing by students, or for me presenting.
I have figured out that I can pass the render function using the knit parameter in the YAML header, but I have to specify to_print = TRUE and set the condition in the ifelse() statement in the output_file correspondingly.
Currently I have:
---
title: "Introduction to R"
subtitle: "Reading and saving data in R"
date: '`r format(Sys.Date())`'
output:
beamer_presentation:
fonttheme: professionalfonts
highlight: tango
includes:
in_header: "../../templatefiles/beamer_header.tex"
template: "../../templatefiles/beamer_template.tex"
incremental: no
keep_tex: yes
slide_level: 3
theme: Warsaw
toc: yes
fontsize: 10pt
fontenc: T1
to_print: TRUE
knit: (function(inputFile, encoding) { rmarkdown::render(inputFile, encoding = encoding,
output_file = file.path(ifelse(TRUE,
gsub("\\..*","_handout.pdf", inputFile),
gsub("\\..*", ".pdf", inputFile)))) })
---
I would like to specify just one parameter that is then used to signify if this is a handout to be printed:
Pseudo-code:
to_print: TRUE
knit: (function(inputFile, encoding) {rmarkdown::render(inputFile, encoding = encoding,
output_file = file.path(ifelse(YAML_PARAM$to_print,
gsub("\\..*","_handout.pdf", inputFile),
gsub("\\..*", ".pdf", inputFile)))) })
Is this possible, or something equivalent that would let me have one .rmd file with a boolean to toggle presentation vs. printing?
