Hi,
I have a data set with structure similar to this:
id user action
1 12 login
2 12 view
3 12 view
4 12 view
5 12 login
6 12 view
7 12 view
8 12 login
I want to create a list of sessions. That means to split table on every
occurrence of "login". Using Java (or some other language), I would
probably iterate through rows and create new List instance on every
"login", but I guess there is more efficient way to do that using R?
Thanks
