xaringan 幻灯片上的水平滚动输出
Horizontally scrollable output on xaringan slides
我想要在水平滚动框中显示 R 命令的输出。代表:
library(ggplot2movies)
head(movies)

如何使输出在 xaringan 幻灯片上水平滚动?
@Yihui Xie 在Github 上已经给出了很好的答案。我只是把它变成一个工作示例。需要注意的是:
1) 可以在 Rmarkdown 中指定 css 作为代码块,或者可以按照以下准则编写自己的 css 文件:https://github.com/yihui/xaringan/wiki。我假设这是一次性的事情,所以为了简单起见,我在 Rmd 文件中包含了 css。
2) pre
元素设置属性后,还需要将width
选项或R
设置大一点,否则head
会换行为您输出。

title: "Horizontal scroll for wide output"
output:
xaringan::moon_reader:
css: ["default"]
nature:
highlightLines: true

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
```{css, echo=FALSE}
pre {
background: #FFBB33;
max-width: 100%;
overflow-x: scroll;
}
```
```{r}
library(ggplot2movies)
op <- options("width"=250) # large number to trick head, otherwise see next slide
head(movies)
options(op) # set options back to default
```
---
```{r}
head(movies) # head with default width, note text gets wrapped. Though you can still scroll horizontally, as an effect of setting `pre`
```
