contingency tables in R

Thanks to Kurt and Mark for their thorough
suggestions.  I look forward to working through their
notes.   I'd like to ask for a bit more clarification
on one point, though.

The most complicated piece of this is contingency
tables done with sample data.  The sampling involves
several strata with different sampling weights. 
Calculating the cell (or row or column)
probabilities
is relatively easy, but the other statistics can be
complicated (the design effect, the finite
population
correction, the various chi^2s, and the standard
errors and confidence intervals). Also, I sometimes
make these tables with summary statistics in place
of
counts or population proportions.  

Both Mark and Kurt noted that they believe that the
pieces I'd need to work in the sampling statistics are
available, I'd just need to piece them together.

What are the pieces I'd use to put this together? 
Thanks in advance for all help - PB.
