Move all code chunks into the appendix.

\section{Computing}

<<setup, include=FALSE>>=
library(knitr)
opts_chunk$set(echo=FALSE) # hide source code in the document
@

You cannot see the source code because echo = FALSE was set globally.

<<a>>=
# chunk a
1+1
@

<<b>>=
# chunk b
2+2
@

<<c>>=
# chunk c
rnorm(10)
@

\appendix
\section{Source code}
Now we show all the code chunks:

<<all-code, ref.label=all_labels(), echo=TRUE, eval=FALSE>>=
@

Of course, you can select labels to include here, e.g. remove the first chunk:

<<some-code, ref.label=all_labels()[-1], echo=TRUE, eval=FALSE>>=
@
