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}.
