coevent

coevent(event, eventTime, window, [orderSensitive=false])

event is a vector indicating events.

eventTime is a temporal or integer vector of the same length as event indicating the timestamps of events.

window is a non-negative integer indicating the length of an interval.

orderSensitive (optional) is a Boolean value indicating whether the order of the two events matters. The default value is false.

Count the number of occurrences of two events within the specified intervals.

Return a table with 3 columns: event1, event2 and hits. The values of event1 and event2 are based on the column event. Column hits is the number of occurrences of the event pair.
