[ESS] configuring ess-pdf-view-pref for forward and inverse search.

[Raghu Naik]

Guys,

I am new to emacs/auctex/ess and ubuntu as well. 

Based on some online search, I have been able to configure my .tex documents
for forward and inverse search with Okular. 

I am having difficulty doing that when I use a .Rnw file. My relevant .emacs
code is below. I would appreciate any help.

I am using the latest versions of emacs, ess, auctex, and R. 


Regards.

Raghu
