Rmarkdown在单独页面上的每个块

Question

我对rmarkdown raport（.pdf）的最高参数是：

---
title: "yyyyyyyyy"
author: "xxxxxxx"
output: pdf_document
classoption: landscape
---

I have some global options

```{r global_options, include=FALSE, echo=FALSE}
knitr::opts_chunk$set(echo=FALSE, warning=FALSE, message=FALSE, fig.width = 14, cache = T)
```
### chunk number 1

```{r}
some r code
```

### chunk number 2

```{r}
some r code
```

### chunk number 3

```{r}
some r code
```

我想控制输出，并将每个块输出在pdf报告中的单独页面上。我如何得到它？
