[R] Any way to add to data frame saved as .rData file?

Hi all,

I've got a script that generates a few moderate-size data frames, and then puts them together into one big data frame at the end in order to write that data frame to disk, so that it may be re-opened later on...

I'm trying to trim down memory requirements in this script, so I was wondering if there was any way to append to a data frame already saved on disk (just like appending to a text file)..all the data frames here have identical row names; what I want to do is to tack on additional columns to a data frame stored in the working directory...

Alternatively, is there another data structure that would allow me to do this (and could preferably be converted to a data frame) ?

Thanks in advance,
