I have no idea wha that chunk is not working but I think you can get the

John,
My original response was too large (3 attached PDF files) and was held for
moderator approval which is no longer needed.
I found the magic solution; looks awkward, but it works.
Near the top of the document (well before any R code) I insert a knitr
chunk containing the directive, opts_chunk$set(echo=FALSE). This is
immediately followed by an ERT box as above. The double whammy prevents R
code from echoing ... except for the contents of the leading chunk itself.
Adding the option, echo=FALSE, to that leading chunk prevents it from
displaying.
Note that both the chunk with opts_chunk$set() and the ERT is required to
prevent R code from displaying. No chunk but ERT box does not stop the
echoing.
Thanks for the pointer,
Rich
