[ESS] Polymode

On Windows I have installed Emacs 24.4 and ESS 14.09 using Vince 
Goulet's distribution. I am having a lot of trouble with processing .Rnw 
and .Rmd files using knitr. I am aware of the M-n w and M-n e commands 
(and the related M-n W and M-n E commands). I am able to weave 
successfully, but exporting (which I understand should use pdfLaTeX for 
a .Rnw file) just seems to hang showing no output and I have no idea 
what is going on. This possibly happens when I have a problem in my file 
(such as a beamer slide which includes verbatim but is not specified as 
fragile), but I really don't know. For .Rmd files I resorted to a 
creating a .bat file using render from the rmarkdown package, which was 
reasonably successful, but was not the best workflow in my view. I would 
really like to be able to just process .Rnw files as previously with M-n 
s followed by M-n P, but I am far from that at present.

Another problem I have at the moment is with M-n w adding '[weaved]' to 
the name of the file. First of all that causes a proliferation of files, 
secondly clicking on the icon to view any resulting pdf causes a file 
not found error because the file name looked for doesn't have '[weaved]' 
added to it.

(To be totally unreasonable, the choice of the word 'weaved' to be added 
to the file name grates on me like finger nails on a blackboard. The 
appropriate adjective for an object which has been created by weaving is 

So. Can anyone explain to me how to process a .Rnw file and view the 
resulting pdf? Also, how to stop the addition of [weaved] to the file name?

Failing that, can anyone explain how to modify auto-mode-alist so that 
instead of polymode, it invokes the old noweb where there is a menu and 
M-n s and M-n P work as before, and I can tangle a file? I am afraid 
that I just don't get lisp programming, so words of one syllable how to 
do that would be good.

Finally, despite what appears above, let me say that I am grateful to 
Vitalie and all the other ESS developers, and in no way wish to 
disparage their efforts. ESS with AUCTeX is just *the* best environment 
for R and TeX and is hugely important to me. Thanks to Vince also for 
his distribution.
