Subject: [Rd] keep.source when semicolons separate statements on the one line
Message-ID: <48B94A4D-DB81-4912-850B-CDB2D7711968@anu.edu.au>

The following is 'semicolon.Rnw'

> \SweaveOpts{engine=R, keep.source=TRUE}
> 
> <<xycig-A, eval=f, echo=f>>=
> library(SMIR); data(bronchit); library(KernSmooth)

> <<xycig-A>>
> @ %

Sweave("semicolon") yields the following 'semicolon.tex'

> Code for panel A is
> \begin{Schunk}
> \begin{Sinput}
>> library(SMIR); data(bronchit); library(KernSmooth)
>> library(SMIR); data(bronchit); library(KernSmooth)
>> library(SMIR); data(bronchit); library(KernSmooth)
> \end{Sinput}
> \end{Schunk}

(I have omitted three blank lines at the start)

With keep.source=FALSE, the commands are split onto 
separate lines, and there is no repetition.
