Try this:

\usepackage{listings}

\lstset{%
	basicstyle=\scriptsize,
	breaklines=true,
	frame=single,
	literate=
		{<-}{$\leftarrow$}{2}
}

\renewcommand\lstlistlistingname{List of listings}


Have a look at the listings package... You can see I'm making the font
size smaller, giving all code a frame, and converting <- into a proper
left arrow (just for R!)

listings is very capable.
