[R] Build a dataframe row by row?

Time for another of my "newbie" questions.

Is it possible to build up a data.frame "row by row" as I go

I'm going to be running a bunch of experiments (many in a loop) to test 
different things.  I'm using AUC as my main performance measure.

My thought was to add a row to a data.frame for each iteration and then 
have a nice summary report at the end.

I found how to import, export, and create from vectors.  I haven't been 
able to find how just make an empty one and add rows as I go.
