是否可以在R Markdown文件中将标题定义为标题？

Question

I want to use tabs in my markdown document. I can apply the .tabset class attribute to my header, that's no issue. However, I would like to apply it to my title. Let's say I have the following code:

---
title: 'Header 1'
author: "Homer Simpson"
date: "4/26/2017"
output: html_document
---

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

# Header 1 {.tabset}

## Header 2

So header 1 appears twice. But I would like to start with Header 2 and not repeat header 1 again. How How would I do that? Thank you!

Avoiding to give a name to the tabset solves you issue:

---
title: 'Header 1'
author: "Homer Simpson"
date: "4/26/2017"
output: html_document
---

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

# {.tabset}

## Header 2

## Header 3

Or similarly avoiding the document title :

---
author: "Homer Simpson"
date: "4/26/2017"
output: html_document
---

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

# Header 1 {.tabset}

## Header 2

## Header 3
