R help - Oct 2007 - inference from dual frame surveys using R

Good afternoon!
   
  My question is more of a "is there a package for doing........?" an
inference regarding the mean, median, regression estimates, etc. by using the
information from dual frame surveys? (this methodology is based on the work of
BANKIER 1986, SKINNER 1991, LOHR and RAO 2000...)
   
  If one has 2 independent studies which both independently measure a trait of a
population, but both of them are constructed from 2 separate frames (which
TOGETHER refer to the population of interest), is there a possibility to infer a
mean, median.. for the population but taking into account all the info,
resulting from the 2 studies, with a specific package in R??
   
  Example:
  "Frame A lists universities offering a PhD in statistics, and frame B
lists universities offering a master's degree in statistics; the frames
overlap (some universities offer both master's and PhD, but we don't
know which) and together cover all the universities offering graduate degrees in
statistics" Lohr and Rao 2000. Now suppose someone wants to study a
characteristic of this population but does so by taking 2 separate samples, each
from its corresponding frame. What package lets me combine the info from the 2
samples for inferring something to the whole population?
   
   
  Thank you and have a great day!!

I don't know of any package that does dual-frame surveys. The survey 
package does not (at the moment).
