使滚动条出现在RMarkdown代码块（html视图） [英] Make Scrollbar appear in RMarkdown code chunks (html view)

问题描述

我使用RStudio和knitr制作了一个RMarkdown文档。我希望我的代码块打印时不会在我创建的html文件上打包文本。有没有一个选项我错过了停止代码的文本包装？到目前为止，我只找到了关于如何删除滚动条的问题，这让我觉得最近可能有些变化。 （RStudio版本0.99.892，R版本3.2.2）Thanks！

简单的示例RMarkdown文档。 （设置部分是默认设置）：

  --- 
 title：停止看起来糟糕的RMarkdown！ 
输出：html_document 
 --- 
 
```{r setup，include = FALSE} 
 knitr :: opts_chunk $ set（echo = TRUE）
```
 
 ####我希望在没有文字换行的情况下打印：
 
```{r} 
x<  -  matrix（nrow = 3，ncol = 20，data = 1）
x 
```
  

如果你运行它，你会看到矩阵x被分成2行。我希望它只是一行，你必须滚动才能看到整个事情。

  --- 
标题：停止看起来糟糕的RMarkdown！ 
输出：html_document 
 --- 
 
< style> 
 pre code，pre，code {
 white-space：pre！important; 
 overflow-x：scroll！important; 
 word-break：keep-all！important; 
 word-wrap：首字母重要; 
} 
< / style> 
 $ b```{r setup，include = FALSE} 
 knitr :: opts_chunk $ set（echo = TRUE）
 options（width = 200）
``` `
 
 ####我希望在没有文字换行的情况下打印：
 
```{r} 
x<  -  matrix（nrow = 3，ncol = 20，data = 1）
x 
```
  

更新版本的R markdown，您可以将< style> 标签替换为：

 ```{css} 
 pre code，pre，code {
 white-space：pre！important; 
 overflow-x：scroll！important; 
 word-break：keep-all！important; 
 word-wrap：首字母重要; 
} 
```
  

I am making an RMarkdown document using RStudio and knitr. I want my code chunks to print without wrapping text on the html file I create. Is there an option I am missing that stops text wrapping of code? So far I have only found questions about how to remove scrollbars, making me think that maybe something has changed recently. (RStudio Version 0.99.892, R Version 3.2.2) Thanks!

Simple example RMarkdown document. (The setup section is the default):

---
title: "Stop looking bad RMarkdown!"
output: html_document
---

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

#### I want this to print without text wrapping:  

```{r}
x <- matrix(nrow = 3, ncol = 20, data = 1)
x
```

If you run that you will see that the matrix x is split into 2 lines. I want it to just be one line that you have to scroll along to see the whole thing.

解决方案

try:

---
title: "Stop looking bad RMarkdown!"
output: html_document
---

<style>
pre code, pre, code {
  white-space: pre !important;
  overflow-x: scroll !important;
  word-break: keep-all !important;
  word-wrap: initial !important;
}
</style>

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
options(width=200)
```

#### I want this to print without text wrapping:

```{r }
x <- matrix(nrow = 3, ncol = 20, data = 1)
x
```

NOTE that with more recent versions of R markdown you can replace the <style> tags with:

```{css}
pre code, pre, code {
  white-space: pre !important;
  overflow-x: scroll !important;
  word-break: keep-all !important;
  word-wrap: initial !important;
}
```
