How can I define the color for the \listings package to display R code in Latex to get the result exactly like in the R Studio platform (example like in the figure)? enter image description here

  • The listings manual describes how to set the style for various things like keywords and comments. You'll need to play with the various options until you get the color scheme you want. If there's something particularly tricky, you should ask about that specifically.

  • I'm not a user of R, but you may be able to look up the colours used within R from the settings panel, as if you were to set up a new style.

  • @TH Do you have the code for defining the code color like in the figure?

    I really dislike listings. Have you considered using minted for this - I believe Pygments (which is actually purpose built for syntax highlighting code) does support R? You could presumably define your own colour scheme if necessary. Commented Jun 8, 2017 at 21:07

I'm not going to find every possible case of how R studio styles code. But maybe this will get you started.

\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}

It may be easier to simply define a new language (or variant) that contains exactly what you want based off of listings's definition which is in lstlang3.sty. The definition for R is this.

I suspect you don't want most of those keywords.

    Why the system informs the error: Option clash for package color

    @Duy, presumably some other package has used \RequirePackage{color} which is causing a conflict. Without the code you're using that causes an error, I'm not sure precisely. One possibility is to provide any necessary xcolor package options to the \documentclass.

There are several ways to include code of any programming language into LaTeX.

Just verbatim

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

enter image description here

Custom listing

\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 package (beautiful Highlighting)

\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}

or choose colour styles for minted

add \usemintedstyle{monokai} in preambula
