knitr - Creating a footer for every page using R markdown

Question

I'm writing a document in R Markdown and I'd like it to include a footer on every page when I knit a PDF document. Does anyone have any idea on how to do this?

Answer 1

Yes, this question has been asked and answered here: Adding headers and footers using Pandoc. You just need to sneak a little LaTeX into the YAML header of your markdown document.

This markdown header does the trick:

---
title: "Test"
author: "Author Name"
header-includes:
- usepackage{fancyhdr}
- pagestyle{fancy}
- fancyhead[CO,CE]{This is fancy header}
- fancyfoot[CO,CE]{And this is a fancy footer}
- fancyfoot[LE,RO]{hepage}
output: pdf_document

Works for me with an Rmd file in RStudio Version 0.98.1030 for Windows.
