# 如何在我的 LaTeX 文档中包含 R 代码片段？

我们推荐 [`listings` 宏包](https://ctan.org/pkg/listings?lang=en) 用于在 LaTeX 文档中插入 R 代码。如果您添加

```latex
\usepackage{listings}
```

到您的导言区，那么您就可以像本示例中所示插入 `R` 代码：

```latex
\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[language=R]
fib <- function(n) {
  if (n < 2)
    n
  否则
    fib(n - 1) + fib(n - 2)
}
fib(10) # => 55
\end{lstlisting}
\end{document}
```

&#x20;[在 Overleaf 中打开此示例](https://www.overleaf.com/docs?engine=\&snip_name=Listing+R+code+in+a+LaTeX+document\&snip=%5Cdocumentclass%7Barticle%7D%0A%5Cusepackage%7Blistings%7D%0A%5Cbegin%7Bdocument%7D%0A%5Cbegin%7Blstlisting%7D%5Blanguage%3DR%5D%0Afib+%3C-+function%28n%29+%7B%0A++if+%28n+%3C+2%29%0A++++n%0A++else%0A++++fib%28n+-+1%29+%2B+fib%28n+-+2%29%0A%7D%0Afib%2810%29+%23+%3D%3E+55%0A%5Cend%7Blstlisting%7D%0A%5Cend%7Bdocument%7D)

此示例生成以下输出：

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-cn/wen-da/29-how-do-i-include-sections-of-r-code-within-my-latex-document.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
