[R] Stacking Vectors/Dataframes

[Laura Quinn]

As our IT man is currently on holiday I am not able to upgrade to version
1.9.0(or 1.9.1) at the moment, and I see that the gregmisc library will
not work on earlier versions (I am using 1.8.0). Does anyone have any
other suggestions how I might be able to acheive this?

Thank you
