How can I get RMarkdown to recognize both fontsize and mainfont when converting to PDF?

An Rmd file with the YAML headers:

---
title: "Untitled"
author: "Me"
date: "September 14, 2015"
output:
  pdfdocument:
    latexengine: xelatex
fontsize: 12pt
---

Correctly renders in 12 computer modern roman when converted to PDF in RStudio. If I add mainfont:

---
title: "Untitled"
author: "Me"
date: "September 14, 2015"
output:
  pdfdocument:
    latexengine: xelatex
fontsize: 12pt
mainfont: Helvetica
---

The PDF is rendered in Helvetica, but at 10 point. I can't get PDF output of 12pt non-CMR. Is there any way to do this?

I've also tried setting the YAML to 12pt and putting \usepackage{helvet} in an external .tex file that gets included in_header, but I get 12pt CMR.

I often encounter problems when trying to use Rmarkdown YAML commands to change font specs. For example, for me neither mainfont nor sansfont command worked to render in Helvetica, or maybe I just fail at figuring out the correct indentation in the YAML header. Besides, I guess you would need to give more information about which OS and R(markdown) Version you're using for someone to help you.

A solution that worked for me (64-bit Linux, R 3.1.2, Rmarkdown 0.7) using CTAN helvet package is this one (let me know it it works for you):

---
title: "Untitled"
author: "Me"
date: "September 14, 2015"
header-includes:
  - \usepackage{helvet}
  - \usepackage[T1]{fontenc}
  - \renewcommand\familydefault{\sfdefault} 
output:
  pdf_document
fontsize: 12pt
---

I derived the solution from this post.
