My question is: is there a way for Rtangle() to *not* print re-used
code chunks? It'd be easy enough to brew up a perl script to do just
this, but if methods exist already, I'd rather use them. My reading of
the help pages and FAQs has missed something, if it's there.
Background:
I have course notes on R, written using Sweave. I want to provide the R
code separately so the course attendees don't have to re-type everthing
in the manual.
In this manual, I typically show a command, then re-use the chunk to
produce a plot. Something like this:
%% first, show how the plot is done...
<<ex.ts.acf.mottle,echo=TRUE,fig=FALSE>>par(mfrow=c(2,2))
mottle.acf <- acf(mottle.t[,1], lag.max=45)
mottle.pacf <- pacf(mottle.t[,1], lag.max=45)
mottle.acf <- acf(mottle.t[,1], lag.max=45, ci.type="ma")
mottle.pacf <- pacf(mottle.t[,1], lag.max=45, ci.type="ma")
@
%% then plot it.
\begin{figure}[tbh]
\centering
<<echo=FALSE,fig=TRUE>><<ex.ts.acf.mottle>>
@
\caption{Autocorrelation plot of the \Data{mottle} dataset.}
\label{fig:ex.ts.acf.mottle}
\end{figure}
%% example ends
Stangle will (correctly) print the <<ex.ts.acf.mottle>> chunk twice,
since it is called twice; once to create it, and once to re-use it.
Cheers
Jason
