【中文标题】Rmd：在带有大都会主题的 Beamer 幻灯片中添加编号的 TOC

【英文标题】：Rmd: Add numbered TOC in Beamer slides with metropolis theme

【发布时间】：2021-11-28 19:00:31

【问题描述】：

我正在创建 Beamer 幻灯片 的 RMarkdown 模板，并使用 metropolis 主题作为基础。

现在，我想要一个编号的目录，我可以通过toc.tex 实现它。但是当我在这里包含它时

beamer_presentation:
  includes:
    in_header:
      - toc.tex

幻灯片的整个格式都消失了，这是我不想要的。 如何保持幻灯片的格式并获得编号的目录

这是我的（最小的工作示例）：

---

slides.rmd:

---
title: "Title"
subtitle:  "Subtitle"
author: "Simon"
institute: "RUB"
date: "September 22, 2021"

output:
  beamer_presentation:
    keep_md: true
    keep_tex: no
    latex_engine: xelatex
    #theme: metropolis
    includes:
      in_header:
          - toc.tex
    slide_level: 2 # which header level should be printed as slides
    incremental: no
header-includes:
  - \usetheme[numbering=fraction]metropolis
  - \definecolorbeaubluergb0.74, 0.83, 0.9
  - \setbeamertemplateframe footer\tiny\textcolorbeaublueConference 56. Jahrestagung der DGSMP, 2021
  - | 
    \makeatletter
    \def\ps@titlepage%
      \setbeamertemplatefootline
    
    \addtobeamertemplatetitle page\thispagestyletitlepage
    \makeatother
---

```r setup, include=FALSE
knitr::opts_chunk$set(echo = FALSE)
```


## Content
\tableofcontents[]

# Level I

Test

## Slide with Bullets

- Bullet 1
- Bullet 2
- Bullet 3

# Slide with R Output

```r cars, echo = TRUE
summary(cars)
```

---

toc.tex:

\setbeamertemplatesection in toc[sections numbered]
\setbeamertemplatesubsection in toc[subsections numbered]

【参考方案1】：

您可以将\includetoc 添加到您的标头包含中：

---
title: "Title"
subtitle:  "Subtitle"
author: "Simon"
institute: "RUB"
date: "September 22, 2021"

output:
  beamer_presentation:
    keep_md: true
    keep_tex: true
    latex_engine: xelatex
    #theme: metropolis
    slide_level: 2 # which header level should be printed as slides
    incremental: no
header-includes:
  - \usetheme[numbering=fraction]metropolis
  - \definecolorbeaubluergb0.74, 0.83, 0.9
  - \setbeamertemplateframe footer\tiny\textcolorbeaublueConference 56. Jahrestagung der DGSMP, 2021

    \makeatletter
    \def\ps@titlepage%
      \setbeamertemplatefootline
    
    \addtobeamertemplatetitle page\thispagestyletitlepage
    \makeatother
    \includetoc
