sessionise: split a series of timestamps (or a series of series) associated with UUIDs, into sessions

Description

sessionise splits timestamps associated with user events into "sessions", enabling the simple calculation of various metrics such as session length or the number of events within a session.

Usage

sessionise(timestamps, threshold = 3600L)

Arguments

timestamps

a list of vectors of second values. These can be extracted by converting POSIXlt or POSIXct timestamps into numeric elements through a call to as.numeric, or with the assistance of

threshold

the threshold, in seconds, for splitting out a new session. Set to 3600 (one hour) by default.

Value

• a list of vectors, each one representing a single session. The returned list can be conveniently passed into session_length or session_events for further analysis.

See Also

session_length for calculating session length, bounce_rate for calculating the bounce rate, and session_events for calculating the number of events in each session.

Examples

#Take the inbuilt dataset and sessionise it
data("session_dataset")
session_dataset$timestamp <- to_seconds(x = session_dataset$timestamp, format = "%Y%m%d%H%M%S")
events_by_user <- split(session_dataset$timestamp, session_dataset$UUID)
sessions <- sessionise(events_by_user)
