How do I get the "number-sections" argument into rmarkdown::render?

[Michael Hannon]

Greetings.  I've been using knitr and pandoc separately to produce HTML (sometimes PDF) documents with a numbered table of contents, something like:

    pandoc -s -S --mathjax --toc --number-sections foo.md -o foo.html

I decided to try the rmarkdown::render approach, and I have to say I think it's a very nice idea.  I can easily get a table of contents via the meta data:

    output:

      html_document:

        theme: cosmo

        toc: yes

But I don't see how to get a *numbered* TOC.  Can somebody enlighten me?  Thanks.

Never mind.  I found the answer:

output:

  html_document:

    theme: cosmo

    toc: yes

    pandoc_args: [

      "--number-sections"

    ]
