Rmarkdown code style in LaTeX

Question

I would like my R code in latex to look like the rmarkdown block of codes: Distinct colours for functions and grey background. I pasted my code between \begin{markdown} and \end{markdown} But this only works for changing latex text to rmarkdown text. I believe I should like in listings or change the background, codecolours manually. Is this possible? Or does someone already programmed rmarkdown code block layout already? Thanks in advance!

Answer 1

The listings package has the option backgroundcolor to change the background of code chunks

\documentclass{article}
\usepackage{xcolor}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[backgroundcolor = \color{lightgray}]
code block
code block
\end{lstlisting}
\end{document}

Trick to make the area bigger:

\documentclass{article}
\usepackage{xcolor}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[backgroundcolor = \color{lightgray},frame=single,framerule=0pt,framesep=10pt]
code block
code block
\end{lstlisting}
\end{document}

Answer 2

To list R code as with knitr in Rmarkdown you can use... knitr:

\documentclass{article}
\begin{document}
<<eval=F>>=
code block
code block
@
\end{document}
