RE: [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!

The table is as follows: Username1 2 Username1 4 Username2 6 Username2 10 Username3 12 Username3 10 Username3 16 Etc The data is sorted by Column 1 (Ie the username) then by columm 2 (The numbers). I want to combine the rows so it would be as follows: Username1 6 Username2 16 Username3 38 Is there easy way using a feature like bind to sum all of collumn two where column 1 is the same? Thanks!
