Question

当我尝试使用 RStudio 中的 RMarkdown 编织pdf时，此代码会产生错误。

如何在 fig.caption 中写一个希腊字母，例如$ \ beta $？

title: "Untitled"
author: "SB"
date: "Thursday, January 29, 2015"
output: 
  pdf_document:
  fig_caption: yes

```{r var, echo=FALSE, fig.cap="Cars variation rate between year $t$ and $t-1$ for $0 < \beta < 1$"}
plot(cars)
```

Answer 1

在R中，字符串内的所有反斜杠都需要加倍。 "\\"变为\。

试试这个：

title: "Untitled"
author: "SB"

  pdf_document:
    fig_caption: yes

```{r var, echo=FALSE, fig.cap="Cars variation rate between year $t$ and $t-1$ for $0 < \\beta < 1$"}
plot(cars)
```
