filter_trace_length: Filter Trace Length

Description

Filters cases on trace_length, using a percentile threshold or interval.

This filter can be used by using an interval or by using a percentage. The percentage will always start with the shortest cases first and stop including cases when the specified percentile is reached. On the other hand, an absolute interval can be defined instead to filter cases which have a length in this interval.

Usage

filter_trace_length(
  log,
  interval = NULL,
  percentage = NULL,
  reverse = FALSE,
  eventlog = deprecated()
)
# S3 method for log
filter_trace_length(
  log,
  interval = NULL,
  percentage = NULL,
  reverse = FALSE,
  eventlog = deprecated()
)
# S3 method for grouped_log
filter_trace_length(
  log,
  interval = NULL,
  percentage = NULL,
  reverse = FALSE,
  eventlog = deprecated()
)

Value

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

Arguments

log: log: Object of class log or derivatives (grouped_log, eventlog, activitylog, etc.).
interval, percentage: Provide either interval or percentage.
interval (numeric vector of length 2): A trace length interval. Half open interval can be created using NA.
percentage (numeric): A percentage p to be used for relative filtering.
reverse: logical (default FALSE): Indicating whether the selection should be reversed.
eventlog: ; please use log instead.

Methods (by class)

filter_trace_length(log): Filters cases for a log.
filter_trace_length(grouped_log): Filters cases for a grouped_log.
