Timestamps and manipulations
...ime a user sees something Vs the last.. and engagment time essentially, i see there is the difftime function, is there a more elegant way of working this out then my thoughts (Pysdo code below) sort data by user_id and Timestamp take the head of user_id as new_time_var take the tail of user_id as new_time_var2 use difftime(new_time_var, new_time_var2, units="secs") Mike [[alternative HTML version deleted]]
