在R Markdown中编译乳胶文档

Question

header-includes:
- usepackage{float}
- usepackage{wrapfig}
- usepackage{graphicx}
- usepackage{lipsum}
- usepackage[fontsize=12pt]{scrextend}
- usepackage{fontspec}
- newcommand*{bibfont}{footnotesize}
- PassOptionsToPackage{dvipsnames}{xcolor} 
- usepackage[dvipsnames]{xcolor}
- usepackage{etoolbox}
- defbibheading{bibliography}[textcolor{Blue}refname]{}
- usepackage{blindtext}
- usepackage{needspace}
- usepackage{mwe}
output: 
pdf_document:
latex_engine: xelatex
fig_caption: true
citation_package: biblatex
bibliography: Gibbs.bib
mainfont: ArialMT
geometry: margin=0.70in
---
