padding_value: automatically generate plausible padding values

Description

padding_value is designed to automatically generate acceptable values for the padding_value argument in session_length. It does this by applying a statistical function to the range of inter-event values within the dataset.

Usage

padding_value(sessions, method, fun, ...)

Arguments

sessions

a list of sessions, generated with sessionise

method

the method to use to generate the value. Options are "geometric mean", "arithmetic mean", "median" or "other" (see below).

fun

the function to apply to generate padding_value, in the event that you choose "other" for method.

...

additional arguments to pass to fun, or the function called by the method.

Examples

#Generate a padding value based on the geometric mean of the known times between events
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)
padding_val <- padding_value(sessions, "geometric mean")
