[ESS] Is ess supposed to help with Sweave documents?

I'm getting into the habit of writing Sweave files instead of R scripts 
with a lot of comments. The pros of this approach are obvious but the 
downside are that I often type things wrong and when I invoke my little 
script that magically transforms this into a pdf this ends in error and 
  Sweave tells me something is wrong in chunk number x.

I would like to be able to load the R code in a file using C-c C-l (so 
Stangle and source instead of just source) just like you would with a .R 
file and then goto the error easily.

I have not entered the dark arts of lisp programming so I'm afraid I can 
not contribute anything more than ideas and feedback at the moment.

Maybe I will someday, since I now find myself spending more than 50 % of 
my working hours using Emacs.

Cheers, Henrik Andersson
