can you help me please how to properly use aggregate function in R? I have data like this:

SPORT   FLOWS
[1,] "Other" "1"  
[2,] "Other" "1"  
[3,] "Other" "1"  
[4,] "Other" "1"  
[5,] "Other2" "1"  
[6,] "Other2" "1"

And I need to get this:

SPORT   FLOWS
[1,] "Other" "4"
[2,] "Other2" "2"

I found, that it can be done with aggregate function, but it doesn't work..

Thank you guys.. I have marked answer which worked for me..
