[R] Table Help

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!
