Yes there are ways to extract parasitics R's.

First off all Cadence is the name of the company.
Cadence Virtuoso is the name of the product family, but
commonly know as the name of the layout editor tool.

You don't do parasitic extraction with a company or
a layout editor tool!

There are two (three, but I forget about Dracula) tools available
form the Company Cadence to do parasitic extraction, Assura and Diva.

With Assura parasitic R extraction is setup together with
C extraction, I don't think that people who simulate and compile the
parasitic models for your process design kit exclude R's.
The option to extract R's can be chosen over the GUI
( Tab "Extraction", Extraction Mode == RC ).

With Diva this has to be defined in your 'divaEXT.rul' file
form your design kit, maybe is it not defined, maybe you have
to set an explicit switch in the GUI for R extraction.  
If you use Diva you should check this file for
'measureResistance' statements, if it contains some
it's likely that you can extract parasitic R's with you rules.
