Can I write a YAML header to produce multiple output formats for an R Markdown file using knitr? I could not reproduce the functionality described in the answer for the original question with this title.
This markdown file:
---
title: "Multiple output formats"
output:
pdf_document: default
html_document:
keep_md: yes
---
# This document should be rendered as an html file and as a pdf file
produces a pdf file but no HTML file.
And this file:
---
title: "Multiple output formats"
output:
html_document:
keep_md: yes
pdf_document: default
---
# This document should be rendered as an html file and as a pdf file
produces an HTML file (and an md file) but no pdf file.
This latter example was the solution given to the original question. I have tried knitting with Shift-Ctrl-K and with the Knit button in RStudio, as well as calling rmarkdown::render, but only a single output format is created, regardless of the method I use to generate the output file.
Possibly related, but I could not identify solutions:
Using R version 3.3.1 (2016-06-21), knitr 1.14, Rmarkdown 1.3

The first code chunk: ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) ``` is used to specify any global settings to be applied to the R Markdown script. The example sets all code chunks as “echo=TRUE”, meaning they will be included in the final rendered version.
R Markdown is an extension of the markdown syntax. R Markdown files are plain text files that typically have the file extension . Rmd . They are written using an extension of markdown syntax that enables R code to be embedded in them in a way which can later be executed.
There are three basic components of an R Markdown document: the metadata, text, and code.
If you are using RStudio, then the “Knit” button (Ctrl+Shift+K) will render the document and display a preview of it.
I actually briefly mentioned in Render all vignette formats #1051 and you missed it:
rmarkdown::render('your.Rmd', output_format = 'all')
It is documented on the help page ?rmarkdown::render.
