如何使用 fancyhdr 包在 RMarkdown 中编辑页脚

Question

我在 RMarkdown 中使用 LaTeX 中的 fancyhdr 包创建了一个 PDF。我正在尝试找到一个解决方案，在该解决方案中，我可以插入一条水平线作为页脚（就在页码上方），以及类似于我所附图像的右上角的页码。另外，有没有一种方法可以将所有超链接（例如目录）的颜色从默认的黑色更改为与图像相同的颜色？

我的 YAML 如下

---
title: "Template for a Dynamic Report for Work"
Uni_Logo: Tex/logo.jpg
Author1: "Tangeni Shatiwa" 
# ----- Manage headers and footers:
#BottomLFooter: $Title$
#BottomCFooter:
#TopLHeader: \leftmark # Adds section name at topleft. Remove comment to add it.
BottomRFooter: "\\footnotesize Page \\thepage" # Add a '#' before this line to remove footer.
addtoprule: TRUE
addfootrule: TRUE               # Use if footers added. Add '#' to remove line.
toc: TRUE
numbersections: TRUE             # Should sections (and thus figures and tables) be numbered?
fontsize: 11pt                  # Set fontsize
linestretch: 1.2                # Set distance between lines.
link-citations: TRUE   # This creates dynamic links to the papers in reference list.
linkcolor: blue
output:
  pdf_document:
    includes:
      in_header: "header.tex"
---

header.tex文件内容如下

\usepackage{fancyhdr}
\usepackage{titling}
\pagestyle{fancy}
\fancyhead{}
\fancyfoot{}
\setlength{\headheight}{50pt}
\lhead{\includegraphics[width = .2\textwidth]{logo.jpg}}
\fancyfoot[R]{\thepage}
\renewcommand{\footrulewidth}{0pt}

\pretitle{%
  \begin{center}
  \LARGE
  \includegraphics[width=4cm,height=6cm]{logo.jpg}\\[\bigskipamount]
}
\posttitle{\end{center}}

TIA！

这是一个示例 rmarkdown 文档和 header.tex 文件。我删除了header.tex 中的徽标行，因为我没有您的徽标。让我知道这是否是您的想法。
