我希望在水平滚动框中显示R命令的输出。 Reprex:

如何在 xaringan 幻灯片上水平滚动输出?

1 个答案:

答案 0 :(得分:1)

@Yihui Xie几乎在Github上提供了答案。我只是在这里将其作为一个工作示例。注意事项:

1)一个人可以在Rmarkdown中将css指定为代码块,或者可以遵循以下准则来编写自己的css文件:https://github.com/yihui/xaringan/wiki。我假设这是一次性的事情,因此为了简单起见,我将Rss文件中的css包括在内。

2)在为pre元素设置属性之后,还需要将width选项或R设置为较大的值,否则head将包装输出为你。

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`
```
