I'm slightly confused with aggregate, will I need to loop it until it stops returning sub lists? Or would I somehow need to convert my username column into a unique list and then do FUN=sum??

Please excuse me, I was just introduced to R yesterday to calculate statistics of over 250 gigs of text we have lol.

Thanks for the reply!

Ben
