Rmarkdown 演示幻灯片行情

Question

我正在使用 rmarkdown 在 RStudio 中进行投影仪演示。我想在演示文稿的顶部获得幻灯片代码。德累斯顿主题应该支持那些股票 Dresden


那么是否有可能通过使用 rmarkdown 来获取这些代码？当我编织 pdf 时，我得到的演示文稿没有幻灯片行情。

示例代码:

---
title: "Example"
output: beamer_presentation
theme: Dresden
---

# R Markdown

This is an R Markdown presentation. 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.

# Slide with Bullets

- Bullet 1
- Bullet 2
- Bullet 3

# Slide with R Code and Output

```{r}
summary(cars)
```

# Slide with Plot

```{r, echo=FALSE}
plot(cars)
```

Answer 1

我认为slide_level选项可能是您正在寻找的:

The slide_level option defines the heading level that defines individual slides. By default this is the highest header level in the hierarchy that is followed immediately by content, and not another header, somewhere in the document. This default can be overridden by specifying an explicit slide_level documentation source

例如使用 slide_level: 2 :

---
title: "Example"
output: 
  beamer_presentation:
    slide_level: 2
theme: Dresden
---

为您提供以下输出



但是，您需要为幻灯片标题提供较低级别的标题，例如

# R Markdown

编辑 要获得与您附加的图像相同的输出，请按以下方式分割演示文稿:

---
title: "Example"
output: 
  beamer_presentation:
    slide_level: 3
theme: Dresden
---
# Section 1
## Subsection 1
### Title A
### Title B
## Subsection 2
### Title A
## Subsection 3
### Title A
### Title B
### Title C
# Section 2
## Subsection 1
### Title A
### Title B

并生成以下演示标题:
