Filter Trace Frequency
Description
Filters the log based the frequency of traces, using an interval or a percentile cut off.
Usage
filter_trace_frequency(
log,
interval = NULL,
percentage = NULL,
reverse = FALSE,
eventlog = deprecated()
)
## S3 method for class 'log'
filter_trace_frequency(
log,
interval = NULL,
percentage = NULL,
reverse = FALSE,
eventlog = deprecated()
)
## S3 method for class 'grouped_log'
filter_trace_frequency(
log,
interval = NULL,
percentage = NULL,
reverse = FALSE,
eventlog = deprecated()
)
Arguments
log |
|
percentage , interval |
The target coverage of activity instances. Provide either |
reverse |
|
eventlog |
Details
Filtering the log based on trace frequency can be done in two ways: using an interval
of allowed frequencies,
or specify a coverage percentage
:
-
percentage
: When filtering using a percentage p%, the filter will return p% of the cases, starting from the traces with the highest frequency. The filter will retain additional traces as long as the number of activity instances does not exceed the percentage threshold. -
interval
: When filtering using an interval, traces will be retained when their absolute frequency fall in this interval. The interval is specified using a numeric vector of length 2. Half open intervals can be created by usingNA
, e.g.,c(10, NA)
will select cases with a trace that occurs 10 times or more.
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.
Methods (by class)
