If you want to insert R code in your LaTeX document, you might want to consider using the “listings” package.
I have written some commands to display my R code in LaTeX in a similar format that my RStudio presents. ▲
\documentclass[a4paper, 12pt]{article} \usepackage[svgnames]{xcolor} \usepackage{listings} \lstset{language=R, % set programming language basicstyle=\small\ttfamily, % basic font style stringstyle=\color{DarkGreen}, otherkeywords={0,1,2,3,4,5,6,7,8,9}, keywordstyle=\color{Blue}, % keyword style commentstyle=\ttfamily \color{DarkGreen}, % comment style backgroundcolor=\color{AliceBlue}, % background colour numbers=left, % display line numbers on the left side numberstyle=\ttfamily\color{Gray}\footnotesize, % line numbers } \title{LaTeX} \author{handsonkeyboard} \begin{document} \maketitle \begin{lstlisting} m1 = matrix(c(1,2,3,4,5,6), nrow=3, ncol=2, byrow = TRUE) m1 # print the matrix \end{lstlisting} \end{document}
