Counting session days
hi,
I have some session data in a dataframe, where each session is recorded with a start and a stop date. Like this:
session_start session_stop
===================
2009-01-03 2009-01-04
2009-01-01 2009-01-05
2009-01-02 2009-01-09
A session is at least one day long. Now I want a dataframe with 'active sessions' per date. Like this:
date active_sessions
=============
