R-Markdown: Serifless字体

Question

我正在使用下面的markdown头。不幸的是，我的pdf中的字体仍然有衬线。我如何才能在全球范围内改变这一点？(我已经尝试过mainfont: Arial和\usepackage{uarial} )

title: "Title"
author: "Author name"
header-includes:
- \usepackage[ngerman]{babel}
- \usepackage{uarial}
output:
  pdf_document:
    toc: yes
    toc_depth: 3
    number_sections: yes
  word_document:
    toc: yes
    toc_depth: '3'
mainfont: Arial
fontsize: 13pt
documentclass: article
