[R] inference from dual frame surveys using R

[Thomas Lumley]

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

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?
