R help - Jul 2015 - Knitr: setting echo = FALSE globally [RESOLVED]

Hi Rich,
It sounds like your approach with the chunks is equivalent to my approach.
Somewhere I remember reading that the global chunk commands apply to everything
'after' the global command--which once one thinks about it is sensible .

Glad it's working.  R +knitr does save a lot of time once you get it
working.

John,

   Yes, it makes sense. So it should work if echo=FALSE is in a chunk _or_ in
the ERT box. Needing to be in both is not expected.

   I'm looking forward to that time savings. :-)

Many thanks,

Rich
