\begin_layout Standard
We can use the
\family typewriter
figure*
\family default
environment in LaTeX so that figures can span over two columns.
Because the output hooks use the
\series bold
framed
\series default
package which does not work well with the
\family typewriter
figure*
\family default
environment, we can either modify the output hooks or use other packages
like
\series bold
listings
\series default
.
For example,
\end_layout
\begin_layout Standard
\begin_inset ERT
status open
\begin_layout Plain Layout
<<chunk-hook, echo=2, tidy=TRUE, tidy.opts=list(width.cutoff=30)>>=
