Subject: [Rd] as.data.frame.table responseName argument (PR#8006)
Message-ID: <20050713114910.616A0A25B@slim.kubism.ku.dk>

You need to call as.data.frame.table directly here.

If we alter the generic we would need to alter all the many methods too 
(including those in various CRAN packages), and I am not sure this would 
be worth it (rather than clarifying the documentation).

This was a user-contributed enhancement that seems to have caused more 
problem that its value.
