为什么我的目录规范不能正常工作？ 来自 Distill for R Markdown

Question

Thank you for your help!

I am having troubles with getting the table of contents (toc) into my Rmarkdown

I have set up the document with the following YAML.. and according to https://bookdown.org/yihui/rmarkdown/html-document.html andhttps://rstudio.github.io/distill/basics.html#table-of-contents I should be able to get a nice toc. But it does not work for me.. Any idea?

With the content of my document like this:

```{r setup, include=FALSE, code_folding=FALSE}
knitr::opts_chunk$set(
  echo = TRUE,
  warning = FALSE,
  message = FALSE,
  comment = "#",
  R.options = list(width = 60)
)
```


```{r ERA and ICRAF logo, fig.align='center', size=20, code_folding=TRUE}
library(cowplot)
ggdraw() + 
  draw_image("/Users/kamaulindhardt_1/Library/Mobile Documents/com~apple~CloudDocs/MSc Wageningen University /Internship ICRAF-ERA/R notes, codes and content/ERA_AGROFORESTRY/./IMAGES/ERA_logo_color.png", width = 0.5) + 
  draw_image("/Users/kamaulindhardt_1/Library/Mobile Documents/com~apple~CloudDocs/MSc Wageningen University /Internship ICRAF-ERA/R notes, codes and content/ERA_AGROFORESTRY/./IMAGES/ICRAF_logo.png", width = 0.5, x = 0.5)
```




# Libraries
```{r setup bookdown, include=TRUE}
library(bookdown)
library(tidyverse)
library(data.table)
library(kableExtra)
library(knitr)
library(here)
#library(cowplot)
```



# Section
## Subsection
### Subsubsection
#### Subsubsubsection

## Quarterly Results {.tabset}

some text

text 1

```{r include=FALSE, layout="l-screen-inset"}
rmarkdown::paged_table(mtcars)
```

```{r, dpi = 200, fig.align='center', fig.cap= 'first'}
plot(cars)
```


text 2

# Section

```{r, fig.align='center', fig.cap= 'second'}
plot(pressure)
```

text 3

# Section 4

## Subsection 4.1

```{r fig.align='center', tidy=TRUE, code_folding=TRUE}
library(ggplot2)
#qplot(x = Sepal.Length, y = Sepal.Width, data = iris, 
#      xlab="Sepal Length", ylab="Sepal Width", 
#      main="Sepal Length-Width", color=Species, shape=Species)

scatter <- ggplot(data=iris, aes(x = Sepal.Length, y = Sepal.Width)) 
scatter + geom_point(aes(color=Species, shape=Species)) +
  xlab("Sepal Length") +  ylab("Sepal Width") +
  ggtitle("Sepal Length-Width")
```

Instead, I get this with nothing inside.

..and there is no content in my table of content??

Answer 1

I think is just a matter of formatting your YAML. When I pasted yours, I had the exact same result as you. However, if I format it like this:

    number_sections: true
    toc_depth: 4
    code_folding: true
  toc_float:

    smooth_scroll: true

I obtain this, with the TOC:

Obviously, I didn't add the images you have.
