Dear R and Sweave users,
Is there a way to have optional sections in a Sweave-generated report
document, complete with section header(s), text and code chunks? In other
words, I'd like for my report to include or omit certain sections based on
the data itself.
For example, If I examine the input dataset early on in the report and set a
variable has_daily_data = TRUE, then I'd like to have a section that looks
at the daily data in detail, with subsections, text and code chunks. What
facilities do I have in Sweave (or odfWeave) for that?
Perhaps, for code chunks, I could wrap all the code inside in
if(has_daily_data) {...}? What about inserting conditional text and
sections? Would it make sense to split the document into subdocuments and
somehow include the optional subdocuments only if needed? How would I go
about that?
Would appreciate any pointers. Thank you,
Aleksey

Its possible to do that using latex if/then/else macros which you can find in latex package ifthen; however, once you are getting to that level of complexity, Sweave is more of a hindrence than a help and is probably no longer the appropriate tool for the job.

That isn't hard to do with Sweave. Within you if branch, you can have your code write out any markup you choose (including \section). For figures, I would suggest writing the image file "manually" (i.e with the code chunk option fig = FALSE) and also write out the \includegraphics statements too. With odfWeave, it is more difficult. Adding sections isn't obvious to me, although odfCat might be able to do it. Figures are more problematic. The way odfWeave works right now, whenever you use fig TRUE in the chunk, odfWeave sets up the figure environment in the document (whether you produce an actual image or not). My recollection was that there wasn't any way around this, but it's been a thorn in my side for a while. I suggest using LaTeX in the short term to do this.
