[R] Is there a bug in CrossTable (gmodels)

[Albert Sorribas]

Library gmodels include a function CrossTable that is useful for
crosstabulation. In the help, it is indicated that one can call this
function as CrossTable(data), were data is a matrix. However, when I try
to use this option, it doesn't help. Any idea? Is there a bug?

Thanks for your help.
