1. 在bookdown的yaml头部添加metadata信息，包括title（书籍标题）、author（作者）、date（日期）、supervisor（指导老师）、institute（学院）等。

title: "我的书籍"
author: "我"
date: "`r Sys.Date()`"
supervisor: "指导老师"
institute: "某某学院"
output:
  bookdown::pdf_book:
    toc: false
    includes:
      in_header: latex/header.tex

2. 创建一个Latex格式的header文件，用于在PDF书籍中添加metadata信息。
