[R] rbinding dataframes

[L C G Rogers]

I've got a data frame which I've split by a factor, 
creating a list of dataframes which I have then done
various operations on individually. I next want to 
recombine the resulting dataframes (still held in a list,
still with the same number of columns with the same names)
and there does not appear to be a `good' way to do this - 
at the moment, I'm using a for-loop with the rbind
command, but this is terribly slow ...  Anyone know a
better way to do it?

Thanks

Chris Rogers
