Add new calculated column to data frame
Hi,
I have a following data set:
id event time (in sec)
1 add 1373502892
2 add 1373502972
3 delete 1373502995
4 view 1373503896
5 add 1373503996
...
I'd like to add new column "time on task" which is time elapsed between two
events (id2 - id1...). What would be the best approach to do that?
Thanks,
Srecko
