\title[knitr, Beamer, and FragileFrame]{A Minimal Demo of knitr with Beamer and Fragile Frames}
\author{Yihui Xie\thanks{I thank Richard E. Goldberg for providing this demo.}}

\begin{frame}{Background}
\begin{itemize}
\item The \textbf{knitr}\textbf{\emph{ }}package allows you to embed R code
and figures in \LaTeX{} documents
\begin{itemize}
\item It has functionality similar to Sweave but looks nicer and gives you
more control
\end{itemize}
\item If you already have Sweave working in \LyX{}, getting \textbf{knitr}
to work is trivial
\begin{enumerate}
\item Install the \textbf{knitr} package in \emph{R}
\item Read \url{https://yihui.name/knitr/demo/lyx/}
\end{enumerate}
\item If you use Sweave or \textbf{knitr} with Beamer in \LyX{}, you must
use the\emph{ FragileFrame} environment for the frames that contain
R code chunks. Let's see if \textbf{knitr} works with Beamer in this
small demo.
\end{itemize}

\section{First Test}
\begin{frame}[fragile]{First Test}
OK, let's get started with just some text:
<<echo=FALSE,results='hide'>>=
# some setup
options(width=60) # make the printing fit on the page
set.seed(1121) # make the results repeatable
@
<<>>=
# create some random numbers
(x=rnorm(20))
mean(x);var(x)
@
BTW, the first element of \texttt{x} is \Sexpr{x[1]}. (Did you notice
the use of\texttt{ \textbackslash{}Sexpr\{\}}?)
\end{frame}
\section{Second Test}
\begin{frame}[fragile]{Second Test}
Text is nice but let's see what happens if we make a couple of plots
in our chunk:
<<boring-plots,fig.width=4,fig.height=4,out.width='.45\\linewidth'>>=
par(las=1,mar=c(4,4,.1,.1)) # tick labels direction
boxplot(x)
hist(x,main='',col="blue",probability=TRUE)
lines(density(x),col="red")
@
\end{frame}
\section{The Big Question}
\begin{frame}{The Big Question}
Do the above chunks work? You should be able to compile the \LyX{}
document and get a nice-looking PDF slide presentation. If not, time
to double-check everything...
