\title{A Minimal Demo of knitr}

\author{Yihui Xie}

\maketitle
You can test if \textbf{knitr} works with this minimal demo. OK, let's
get started with some boring random numbers:

<<boring-random>>=
set.seed(1121)
(x=rnorm(20))
mean(x);var(x)
@

The first element of \texttt{x} is \Sexpr{x[1]}. Boring boxplots
and histograms recorded by the PDF device:

<<boring-plots, fig.width=4, fig.height=4, out.width='.4\\linewidth'>>=
## two plots side by side (option fig.show='hold')
par(mar=c(4,4,.1,.1),cex.lab=.95,cex.axis=.9,mgp=c(2,.7,0),tcl=-.3,las=1)
boxplot(x)
hist(x,main='')
@

Do the above chunks work? You should be able to compile the \TeX{}
document and get a PDF file like this one: \url{https://github.com/yihui/knitr/releases/download/doc/knitr-minimal.pdf}.
