R markdown - how to switch font to Times New Roman?

Question

I gave up. I can't find any working solution to change font type in my R Markdown document. I tried a lot of stuff, for example:

---
output: word_document    
sansfont: Calibri Light
---

But RStudio just ignores it. Can you help me? I need Times New Roman font in my pdf/word document.

Regards

Another option: for a pdf document, I used:

output: pdf_document
fontfamily: arev

In my YAML header.

Answer 2

This worked for me. Try using mainfont instead of sansfont, and set latex_engine to either xelatex or lualatex.

output: 
  pdf_document:
    latex_engine: xelatex
mainfont: Times New Roman
