[ESS] ess-pdf-viewer-pref no longer used?

[Tyler Smith]

Hi,

I have ess-pdf-viewer-pref set to "emacsclient". This used to have 
the effect of opening pdfs in Emacs. It doesn't work anymore, and 
pdfs opened from ESS (e.g. vignettes) are now opened in the 
default pdf program for my OS (which is Evince on my machine).

Searching the code, the varaible `ess-pdf-viewer-pref` no longer 
exists, except for a few mentions in the changelog. None of the 
mentions indicate it has been deprecated. I didn't find any 
reference to pdfs in the manual either.

What is the current way to configure which programs are used to 
open pdfs from ESS?

Best,

Tyler
