rbind with a NULL data.frame

["Wright, Kevin" <WRIGHTKEVI@phibred.com>]

I'm interested in using rbind inside a loop (I know, poor programming....)
and would like to somehow intialize a data.frame to which I can rbind a row
every iteration.

This works with matrices, for example:

A_NULL
rbind(A, 1:5)

I cannot make it work with data.frame

Any suggestions will be appreciated.

I will summarize any useful responses which are not already posted to
S-news.

Thanks,
