在 Latex 中插入 R 代码

如何定义 \listings 包的颜色以在 Latex 中显示 R 代码，从而获得与 R Studio 平台完全相同的结果（如图中的示例）？在此处输入图片描述

答案1

我不会找出 R Studio 如何设计代码的所有可能情况。但也许这会给你一些启发。

\documentclass{article}
\usepackage[svgnames]{xcolor}
\usepackage{listings}

\lstset{language=R,
    basicstyle=\small\ttfamily,
    stringstyle=\color{DarkGreen},
    otherkeywords={0,1,2,3,4,5,6,7,8,9},
    morekeywords={TRUE,FALSE},
    deletekeywords={data,frame,length,as,character},
    keywordstyle=\color{blue},
    commentstyle=\color{DarkGreen},
}

\begin{document}
\begin{lstlisting}
#Calculate CE for each counterparty
Value.A <- data.frame() #MTM value of each contract within cp A
# ...
for(i in 1:length(foo)){
  if(isTrue(as.character(portfolio_data[i,1])=="A")==TRUE){
    # ...
  }
}
\end{lstlisting}
\end{document}

可能更容易的是，只需根据listingslstlang3.sty 中的定义定义一种包含您想要的内容的新语言（或变体）。R 的定义如下。

我怀疑您不想要大多数这些关键词。

有多种方法可以将任何编程语言的代码包含到 LaTeX 中。

只是逐字逐句

    \begin{verbatim}
    # Creating a Graph
    attach(mtcars)
    plot(wt, mpg)
    abline(lm(mpg~wt))
    title("Regression of MPG on Weight")
    \end{verbatim}

自定义列表

\documentclass{article}
\usepackage{listings}
\usepackage{xcolor}

\definecolor{codegreen}{rgb}{0,0.6,0}
\definecolor{codegray}{rgb}{0.5,0.5,0.5}
\definecolor{codepurple}{rgb}{0.58,0,0.82}
\definecolor{backcolour}{rgb}{0.95,0.95,0.92}

\lstdefinestyle{mystyle}{
    backgroundcolor=\color{backcolour},   
    commentstyle=\color{codegreen},
    keywordstyle=\color{magenta},
    numberstyle=\tiny\color{codegray},
    stringstyle=\color{codepurple},
    basicstyle=\ttfamily\footnotesize,
    breakatwhitespace=false,         
    breaklines=true,    captionpos=b,                    
    keepspaces=true, numbers=left,                    
    numbersep=5pt, showspaces=false,                
    showstringspaces=false, showtabs=false, tabsize=2}
\lstset{style=mystyle}

\begin{document}
\begin{lstlisting}[language=R]
# Creating a Graph
attach(mtcars)
plot(wt, mpg)
abline(lm(mpg~wt))
title("Regression of MPG on Weight")
\end{lstlisting}
\end{document}

Minted 包装（精美亮点）

\documentclass{article}
\usepackage{minted}
\begin{document}
\begin{minted}{R}
# Creating a Graph
attach(mtcars)
plot(wt, mpg)
abline(lm(mpg~wt))
title("Regression of MPG on Weight")
\end{minted}
\end{document}

或选择 minted 的颜色样式
