R help - Jan 2014 - KnitR/RMarkdown: Is there a way to not print a section of the document?

I've been looking through the R documents to see if there's a way to not
output certain chunks of code. I'm trying to present a document to a team
of folks that won't necessarily be interested in the line-by-line code,
though they are interested in the charts, etc. Thus, I'd like to not output
certain chunks of code. Is there a way to suppress sections?

Thank you.

In the chunk options, you can use the argument echo = FALSE to
suppress display of the R code in the output.
<< echo = FALSE>># R code
@
This will still print out results from R that would be sent to the
command line (like print() statements, cat() statements, results from
summary(), etc), but the rest of the code in the chunk would be hidden
from the output document.

To make it easier to turn many code chunks on and off at once, define
a variable as TRUE/FALSE early in the document, and then use that
variable as the argument in the subsequent chunk options:

<<echo = FALSE>>showcode = FALSE
@

Every other chunk gets this argument:
<< echo = showcode>># R code. If showcode is FALSE, this code would
be run, but not
displayed in the output document.

Hi

I use Sweave and have a master Rnw file and parent files.
If there are large chunks I split them up and then just put a % in front of
the \SweaveInput if unwanted.

Otherwise I split up the tex files with \input and \includeonly

You could get into the chunk options and change things there but that is
fiddly if you want to reuse
