MikTex lstlisting package with quotes

Question

I'm using the beamer class to create slides and using the lstlisting package inside a colorbox. Below is a reproducible example showing my problem when using pdflatex. I'm trying to use quotes (") as in the line read.csv(c:'//path') and the compiler breaks. Things works when the quotes are removed.

Does anyone see a way to solve that problem?

\documentclass[]{beamer}
\usepackage{colortbl} 
\usepackage{bm}
\usepackage{color}
\usepackage{amssymb,amsmath}
\usepackage{mathtools} 
\usepackage{float}
\usepackage{algorithm}
\usepackage[noend]{algpseudocode}
\usepackage{listings}
\lstset{basicstyle=\ttfamily} 
\usepackage{tcolorbox}
\usepackage{graphicx}
\usepackage{fancybox}
\usepackage{hyperref}
% For formatting R code
\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},
    xleftmargin=.0in,
    breaklines=true,
    xrightmargin=.25in
}
