# 我該如何在我的 LaTeX 文件中加入部分 R 程式碼？

我們建議使用 [`listings` 套件](https://ctan.org/pkg/listings?lang=en) 用於在 LaTeX 文件中加入 R 程式碼。如果你加入

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

到你的前言區，就可以接著插入 `R` 程式碼，如本範例所示：

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

[在 Overleaf 中開啟此範例](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)

此範例會產生以下輸出：

# 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-tw/wen-yu-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.
