Yes it works, why it shall not work? The question is if it do what you 
expect to do. Your command sums counts which belongs to same bin, EVDO_Rev 
and Session_Setup, if it is what you want.

If by chance you want to sum counts which have FCA 4, 5 or 6 then

by = list (FCA = FCA %in% c(4,5,6)

could be one option.
