John,

   Crotchety is appropriate for situations like this.

   The above _almost_ works. Attached three PDF files show the results of
tests, all with the LaTeX code inserted.

   sample-no-chunk.pdf: removing chunk2 with its contents,
opts_chunk$set(echo=FALSE), did not keep the R code from displaying.

   sample-chunk-2-above.pdf and sample-chunk-2-below.pdf: chunk2 was prior
to, and following, the LaTeX code and all other R code did not echo, only
the chunk2 code displayed.

Thanks,

Rich
