Help with aggregation
...the
dataframe,
I want to take the max value of a user, and then apply this max value back
against all id's that match (i.e a one to many matching)
Can anyone offer any advice?  is there a better way of doing this?
Dummy data and code are listed below:-
dataset is called Mcookie
user_id        c_we_conversion
    1                     1
