filter_endpoints: Filter: Start and end activities

In gertjanssenswillen/edeaR: Exploratory and Descriptive Event-Based Data Analysis

Description

Filters the log based on a provided set of start and end activities

Usage

filter_endpoints(eventlog, start_activities, end_activities, percentage,
  reverse, ...)

## S3 method for class 'eventlog'
filter_endpoints(eventlog, start_activities = NULL,
  end_activities = NULL, percentage = NULL, reverse = FALSE, ...)

## S3 method for class 'grouped_eventlog'
filter_endpoints(eventlog,
  start_activities = NULL, end_activities = NULL, percentage = NULL,
  reverse = FALSE, ...)

ifilter_endpoints(eventlog)

Arguments

eventlog	The dataset to be used. Should be a (grouped) eventlog object.
start_activities	A vector of activity identifiers, or NULL
end_activities	A vector of activity identifiers, or NULL
percentage	A percentage p to be used as percentile cut off. When this is used, the most common endpoint-pairs will be selected until at least the p% of the cases are selected.
reverse	Logical, indicating whether the selection should be reversed.
...	Deprecated arguments.

Details

The filter_endpoints method filters cases based on the first and last activity label. It can be used in two ways: by specifying vectors with allowed start activities and/or allowed end activities, or by specifying a percentile. In the latter case, the percentile value will be used as a cut off. For example, when set to 0.9, it will select the most common endpoint pairs which together cover at least 90

Value

When given an eventlog, it will return a filtered eventlog. When given a grouped eventlog, the filter will be applied in a stratified way (i.e. each separately for each group). The returned eventlog will be grouped on the same variables as the original event log.

Methods (by class)

• eventlog: Filter event log

• grouped_eventlog: Filter grouped event log stratified
