[R] Estimating the standard error when you have sampling weights.

[David Winsemius]

I am having difficulty thinking that you cannot find general material  
by doing a Google search, but can tell you from memory that the US  
National Center for Health Statistics publishes on the WWW quite a bit  
of information about their survey methods.

For an R-centric answer: Have you looked at the survey package that  
Lumley created?

Doing  help.search("sampling") I also see that wtd.mean is available  
in Harrell's Hmisc. The help page for that function also has useful  
links.
