如何在 R Markdown 中使用 Latex 动态着色页面的一侧

Question

我正在尝试使用 R Markdown 和 Latex 准备纸质模板。我一边学习一边学习，对我来说下一个挑战是能够动态地对页面的侧面进行着色。换句话说，我希望能够对具有奇数页码的页面右侧进行着色，并且我希望能够对具有偶数页码的页面左侧进行着色。到目前为止，我已经找到了一种能够不断为页面右侧着色的解决方案。这是到目前为止我的 .Rmd 代码；

## R Markdown

This is an R Markdown document. Markdown is a simple formatting     syntax for authoring HTML, PDF, and MS Word documents. For more     details on using R Markdown see <http://rmarkdown.rstudio.com>.     When you click the **Knit** button a document will be generated     that includes both content as well as the output of any     embedded R code chunks within the document. You can embed an R     code chunk like this:

而

customized_paper_template.tex

文件的内容是这样的；

\usepackage{fontspec}
\usepackage{geometry}
\geometry{a4paper, margin=1in} % Default geometry for the title     page
\usepackage{setspace}
\usepackage{xcolor}
\usepackage{eso-pic}
\usepackage{fancyhdr}
\usepackage{sectsty}

\renewcommand{\baselinestretch}{1.25}

% Set body text font
\setmainfont{Kepler Std Light Semicondensed}

% Set title fonts
\newfontfamily\titlefont{Tiempos Headline}

% Set hyperlink fonts
\newfontfamily\urlfont{Roboto Slab}
\newfontfamily\linkfont{Roboto Slab}


% Set the font size for the document
\AtBeginDocument{\fontsize{12pt}{14pt}\selectfont}

% Define title formatting
\usepackage{titlesec}
 \titleformat{\section}
  {\normalfont\LARGE\titlefont} % Title style
  {\thesection} % Section number
  {1em} % Space between number and title
  {} % No additional formatting before the title text
   [{\titlerule[0.5pt]}] % Add a line under the title with     0.5pt thickness

\titleformat{\subsection}
  {\normalfont\LARGE\titlefont} % Title style
  {\thesubsection} % Section number
  {1em} % Space between number and title
  {} % No additional formatting before the title text
  [{\titlerule[0.5pt]}]  % Add a line under the title with     0.5pt thickness

\titleformat{\subsubsection}
  {\normalfont\Large\titlefont} % Title style
  {\thesubsubsection} % Section number
  {1em} % Space between number and title
  {} % No additional formatting before the title text
  [{\titlerule[0.5pt]}]  % Add a line under the title with     0.5pt thickness


% Add headers
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{} % clear all header and footer fields
\fancyhead[L]{Course Name} % section title on the left
\fancyhead[R]{Author Name} % fixed text on the right
\fancyfoot[C]{\thepage} % page number in the center of the     footer  
% Remove header line
\renewcommand{\headrulewidth}{0pt}  

生成的 pdf 输出也是这样的；

我更喜欢一个解决方案，我可以将其写入customized_paper_template.tex 文件中，这样主.Rmd 文件就不会变得混乱。提前感谢您的建议。
