Proportions again

Several people have alrady answered you by this time and
in addition to their answers you might also be interested
in CrossTable in package gregmisc.

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
