Nope. That's what I also thought, but I was really amaized when discovered that
there is no need for this. You only need to set up noweb stuff as mentioned at

<http://thread.gmane.org/gmane.editors.lyx.general/18847>

and use article(noweb) for document style. Then everything (export and view 
directly from LyX GUI) just works. As I said I was really surprised with it. 
Try with SweaveNoweb.lyx and you will see. This way, one can skip my silly
Sweave.sh ;)

I also prefer Emacs this days, and I really did not spend a lot on this LyX
feature, but since it is "so easy" I just couldn't retain to share.
