R devtools: create both html and pdf of vignettes

Question

I have written a tutorial in vignette form for one of my packages.

It works fine, but it only creates the html version of the vignette. Is there a way I can create both the html and the pdf version of my vignettes?

I have tried to append rmarkdown::pdf in the output field of my .Rmd file, but it didn't work.

Add all the formats you want to the YAML header (with the "default" one being the first) and do rmarkdown::render("YOUR_RMD_FILE", "all") – Edric

how do I add them? In the output field, I do I set two formats? – Azobenzene

Answer 1

This is what I added in the header of my vignette.

output:
  knitr:::html_vignette:
    toc: true
    css: custom.css
    fig_caption: yes
  pdf_document:
    highlight: null
    number_sections: yes

and the I used the command from hrbrmstr above which produces a PDF file.

rmarkdown::render("vignettes/itkr.Rmd", "all")
