rmarkdown: use Roman numerals for section numbers?

[Michael Hannon]

Greetings.  I've been given a document format that I'm required to follow, and it uses Roman numerals for section numbers.  I've got an Rmd document that I "typeset" with the render command in the rmarkdown package.  It works nicely, but it has Arabic numerals for the sections.  Is there any way to get Roman numerals?  In LaTeX it would be something like:

\documentclass{article}
\renewcommand{\thesection}{\Roman{section}} 
\renewcommand{\thesubsection}{\thesection.\Roman{subsection}}

Here's the info about the rmarkdown that I'm using:

Package:              rmarkdown
Type:                 Package
Title:                R Markdown Document Conversion
Version:              0.1.6
Date:                 2014-01-26




And the version of R:

> sessionInfo()
R version 3.1.0 (2014-04-10)
Platform: x86_64-redhat-linux-gnu (64-bit)




Thanks.

I do not think it is straightforward to change the section number
style, but it is always possible to define your own template:

almost always the answer when you ask for more than Pandoc's Markdown.

Thanks, Yihui. The job I have at the moment is short-term enough that
I think I'll just put in the Roman numerals by hand.
