[R] Contingency tables example

[jim holtman]

Without giving help on a potential homework problem, I would suggest
that after each step you examine the object you are
creating/modifying.  This is a basic debugging technique that will
help you out in the future.  If you have a multi-step problem (as
almost all are), then you may have to go step-by-step and track down
when the problem is.  It should be obvious where your problem is if
you follow these instructions.
