Omigod! The archival links shows that this was the same problem that
caused me to give up on Sweave about 6 years ago. I guess I never
properly assimilated Brian Ripley's comments at the time.
I finished up doing this:
\begin{verbatim}
> height = scan()
1: 64 62 66 65
5: 62 69 72 72 70
10:
Read 9 items
> part = scan(what = character(0))
1: "Soprano" "Soprano" "Soprano"
4: "Alto" "Alto" "Tenor"
7: "Tenor" "Bass" "Bass"
10:
Read 9 items
\end{verbatim}
<<echo=FALSE,results=hide>>=
height <- c(64, 62, 66, 65, 62, 69, 72, 72, 70)
part = c("Soprano","Soprano", "Soprano",
"Alto", "Alto", "Tenor",
"Tenor", "Bass", "Bass")

which does give the output I want (though in a different style) and
leaves the R session in the state that I want.
If you the look to be the same as with other chunks, you should use the
Sinput, Soutput and possibly Schunk environments. (Schunk normally does
nothing, but you might have customized it.) That is, write your stuff as
\begin{Schunk}
\begin{Sinput}
> height = scan()
1: 64 62 66 65
5: 62 69 72 72 70
10:
\end{Sinput}
\begin{Soutput}
Read 9 items
\end{Soutput}
\begin{Sinput}
> part = scan(what = character(0))
1: "Soprano" "Soprano" "Soprano"
4: "Alto" "Alto" "Tenor"
7: "Tenor" "Bass" "Bass"
10:
\end{Sinput}
\begin{Soutput}
Read 9 items
\end{Soutput}
\end{Schunk}
(I suppose it's debatable whether lines to scan() should be typeset as
input or output.)

Thanks for all your help.

Both suggestions generate similar errors to those of the original

You are teaching them about R or about Sweave? You are setting up code
that is designed to run at an open console session, but submitting it to
a batch process.

After reading that I am wondering if you could set up a textConnection
first and then scan from that?
> con <- textConnection("64 62 66 65 62\n69 72 72 70")
> scan(file=con)
