使用 Rmarkdown 在 Beamer 演示文稿中插入导航栏

Question

我正在尝试在 R Markdown 中制作 Beamer 演示文稿，您可以在下面看到代码是如何开始的：

---
title: "Test presentation"  
author:   
  - Loana  
institute:   
  - Supervised by   
  - University  
date: Academic year 2017-2018  
output:   
  beamer_presentation:  
    incremental: false  
    theme: "Frankfurt"  
    colortheme: "beaver"  
    toc: true   
    slide_level: 5
    keep_tex: true
header-includes: 
- \AtBeginSubsection{} 
---

此代码给出如下图所示的输出

但是我的意图是在幻灯片的右上角有导航栏，所以有人可以帮我怎么做吗？

Answer 1

以下是您想要的输出吗？

如果是这样，创建一个文件 header.tex 包含以下内容（取自 https://tex.stackexchange.com/a/35637/181010）

\setbeamertemplate{navigation symbols}{}
\makeatletter
\setbeamertemplate{footline}
{%
  \pgfuseshading{beamer@barshade}%
  \ifbeamer@sb@subsection%
  \vskip-9.75ex%
  \else%
  \vskip-7ex%
  \fi%
  \begin{beamercolorbox}[ignorebg,ht=2.25ex,dp=3.75ex]{section in head/foot}
  \insertnavigation{\paperwidth}
  \end{beamercolorbox}%
  \ifbeamer@sb@subsection%
  \begin{beamercolorbox}[ignorebg,ht=2.125ex,dp=1.125ex,%
                         leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
  \usebeamerfont{subsection in head/foot}\insertsubsectionhead
  \end{beamercolorbox}%
  \fi%
}%
\setbeamertemplate{headline}{%
  \hskip1em\usebeamercolor[fg]{navigation symbols dimmed}%
}
\makeatother

然后将 header 添加到 .Rmd 的 yaml 中：

---
title: "Test presentation"  
author:   
  - Loana  
institute:   
  - Supervised by   
  - University  
date: Academic year 2017-2018  
output:
  beamer_presentation:  
    incremental: false  
    theme: "Frankfurt"  
    colortheme: "beaver"  
    toc: true   
    slide_level: 5
    keep_tex: true
header-includes: 
  - \AtBeginSubsection{} 
  - \input{header.tex}
---
