Specifying multiple concurrent output formats in knitr (new)

Is it possible to write a YAML header to generate multiple output formats for an R Markdown file using knitr? I have not been able to reproduce the functionality described in the answer to 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

      

        
        
        
      

    

creates a PDF file, but not an 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

      

        
        
        
      

    

creates HTML file (and md file) but not pdf file.

This last example was the solution asked by the original question. I tried knitting with Shift-Ctrl-K and Knit button in RStudio as well as calling rmarkdown::render

, but only one output format is generated regardless of the method I use to create the output file.

It might be related, but I couldn't figure out solutions:

• How do I create R vignettes in multiple formats?
• Check all vignette formats # 1051
• knitr :: pandoc cannot create pdf and tex files with one config # 769
• Several formats for pando # 547
• Multiple Output Formats Allusion in RStudio's 3-Year Blog

Using version R 3.3.1 (2016-06-21), knitr 1.14, Rmarkdown 1.3
