John,

Take a look at the 'catspec' package by John Hendrickx on CRAN. There  
is a function in there called 'ctab', which if memory is correct, will  
do what you want. John had originally posted his code here:

   https://stat.ethz.ch/pipermail/r-help/2003-February/030400.html

and it has been updated to some extent in the package since then.

HTH,
