Gabor,

Thanks for pointing out CrossTable().

Just as a quick heads up/clarification for Carlos, CrossTable() is
designed to cross-tabulate two vectors and generate counts,
row/column/table proportions and other results from the 2 dimensional
cross-tab in a (hopefully) nicely formatted fashion.

It is not presently designed to handle generating proportions from the
tabulation of a single vector with repeating values (such as Carlos'
example) and will generate an error message if a single vector is
passed.

In that scenario, as many folks have already recommended, the
combination of table() and prop.table() would be preferred.

HTH,

Marc Schwartz
