How to write an R example in Latex file

I am writing a latex file in Rstudio, and need to present an R example for an R package developed by myself. I noticed the published paper often has a format for the example as shown below, but I am not sure what functions they were using to generate this style, such as R>... How do we produce something like this?

  • I am unsure which OS you are using; here is an example to help guide the way.

    [![\documentclass{article}
\usepackage{listings}
\usepackage{xcolor}
\usepackage{parskip}  
\usepackage{hyperref}

% Define colors
\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{linkcolor}{rgb}{0,0,0.8}  % Dark blue for links

\hypersetup{

\maketitle

\noindent Here is an example of R code formatted in a console-style using the listings package:

\begin{lstlisting}\[style=RConsoleStyle\]
(*@\textcolor{codegray}{R>}@*) library("simexaft")
\end{lstlisting}

Next, load the data that are properly organized with the variable names specified. In the example here, the data set named as BHS is included by issuing

\begin{lstlisting}\[style=RConsoleStyle\]
(*@\textcolor{codegray}{R>}@*) data("BHS")
(*@\textcolor{codegray}{R>}@*) dataset <- BHS
(*@\textcolor{codegray}{R>}@*) dataset$SBP <- log(dataset$SBP - 50)
\end{lstlisting}

    Here is the output:

    I hope this points you in the right direction.
