Sorry for the typo - of course ESS 5.3.7.

   (shell-command (concat "start \"" pdfviewer "\" \"" namestem ".pdf\"")))

works just fine for me. Thank you.

Also I've noticed that "ess-swv-latex" as opposite to "ess-swv-pdf" does  
leave the *Tex-tex-output* on top of my *.Rnw file. This is because   
(switch-to-buffer buf) is not included before  (display-buffer tex-buf).  
If is not an original intention may be that also could be changed.
