\begin_layout Title
Using subfloats in LyX with knitr
\end_layout

\begin_layout Author

\begin_layout Standard
If you insert a float figure inside a float figure in LyX, you will get
 subfloats.
 To make sure the two subfloats can stand side by side, you have to:
\end_layout

\begin_layout Enumerate
remove new lines between the two subfloat environments in LyX (if you are
 not sure if there are blank lines between them, check the LaTeX source);
\end_layout

\begin_layout Enumerate
use the chunk option 
\family typewriter
echo=FALSE
\family default
 to hide the R source code in the output;
\end_layout

\begin_layout Enumerate
set 
\family typewriter
out.width
\family default
 to be less than half of the linewidth if you do not want the sub figures
 to exceed the page margin;
\end_layout

\begin_layout Enumerate
most importantly, leave a blank line in the beginning of the subfloat environmen
t, so that 
\family typewriter
<<>>=
\family default
 starts in a new line and 
\series bold
knitr
\series default
 can recognize it;
\end_layout
