Sidestepping the issues you mention, I find org-mode (with org-babel)
perfectly fine for producing PDF, LaTeX, and HTML files for my
workflow. I write code snippets surrounded by text and equations, run
them individually when working on the project, then compile the whole
file when done. If you want both PDF and HTML, use SVG for graphs,
otherwise PDF is fine. C-c ' in org-mode will open your code in an ESS
buffer, and you can work on it as usual.

One can start compilation with C-c C-c as usual and choose either to only sweave the file or to sweave and then compile to PDF with LaTeX. The TeX engine chosen on the AUCTeX side is honoured as seen to be the encoding of the file. Nice work ESS people!
> However, when .Rnw files are associated with poly-noweb+r-mode (from polymode) as is the case in my distribution, the whole ESS and AUCTeX integration seems to be disabled. I think this is unfortunate. Enough to strongly consider removing the default association in my distribution. If one wants to use the whole polymode approach for what I'd consider "pure" Sweave files, one would need to opt-in via ~/.emacs.

> Third, pandoc. I discovered that RStudio ships with a version. [And also that rmarkdown has special bindings to find the RStudio version of pandoc, but otherwise lets you on your own. Not impressed.] I thought that doing the same for Emacs could be nice to have a distribution fully markdown and rmarkdown ready. I can tell markdown-mode where to find a parser by setting 'markdown-command'. However, rmarkdown::render() does look at this variable and relies on pandoc being on the shell's path.
