Run RMarkdown with arguments on the command line

Question

I\'m trying to run a Rmarkdown file (myfile.Rmd) from the command line terminal. This file needs to take an argument to work. We can use this simple file as an exam

Answer 1

Adding the myarg object as a parameter is the way to go:

Rscript -e "rmarkdown::render('example.Rmd',params=list(args = myarg))"

And then add the parameter to your Rmd file:

---
title: "Simple example"
output:
  pdf_document: default
params:
  args: myarg
---
