html - RMarkdown 文件中 R 代码块输出的宽度 knitr-ed 到 html

Question

问题:

在 html 文件中设置 r 代码输出宽度的当前工作解决方案是什么？我想将宽度设置为大一些，并在 html 输出中使用 slider 。

options(width = XXX) 似乎不再起作用了。

示例:

---
title: "Width test"
output:
  html_document:
    theme: default
---
```{r global_options, echo = FALSE, include = FALSE}
options(width = 999)
knitr::opts_chunk$set(echo = FALSE, warning = FALSE, message = FALSE,
                      cache = FALSE, tidy = FALSE, size = "small")
```
```{r}
sessionInfo()
```
```{r}
dataM <- matrix(rnorm(100, 5, 2), ncol = 15)
dataM
```

结果:

上面屏幕截图中的 sessionInfo() 输出。

如果 pre block 溢出，您可以使用它来水平滚动。

title: "Width test"
output:
  html_document:
    theme: default
---

<style>
pre {
  overflow-x: auto;
}
pre code {
  word-wrap: normal;
  white-space: pre;
}
</style>

```{r global_options, echo = FALSE, include = FALSE}
options(width = 999)
knitr::opts_chunk$set(echo = FALSE, warning = FALSE, message = FALSE,
                      cache = FALSE, tidy = FALSE, size = "small")
```
```{r}
sessionInfo()
```
```{r}
dataM <- matrix(rnorm(100, 5, 2), ncol = 20)
dataM
```

对于可滚动高度，创建一个具有最大高度和 overflow-y: auto; 或 overflow-y: scroll;

的容器 div
