I have a similar issue coming up, my current plan was to write a Sweave document which would run on the last available saved reactives. This creates a .tex document which can be converted to a .pdf with a pdflatex command (running the command twice in order to give figures their proper figure numbers, if applicable when not hard coded into it).
Though if there was a better solution, I would love to see it- I would be especially interested in a mechanism which would capture all of the tabs simultaneously to take a snapshot, both visually and code-wise, of all the selected options/subsetting to create a reproducible document.
