Hi,
I'm looking for a function that will sum a variable across all
observations by identifier.
For example, if I have
ID A
1 1
1 0
2 1
2 2
I would like a function that would give me:
SumByID=function(A,ID)
SumbyID would be equal to 1 for all observations with ID=1 and 3 for
all observations with ID=2 .
Thanks very much,
Rachel
