Eventlog

A function to instantiate an object of class eventlog by specifying a data.frame or tibble and appropriate case, activity and timestamp classifiers.

Usage

eventlog(
  eventlog,
  case_id,
  activity_id,
  activity_instance_id,
  lifecycle_id,
  timestamp,
  resource_id,
  order,
  validate
)

ieventlog(eventlog)

Arguments

eventlog

The data object to be used as event log. This can be a data.frame or tibble.

case_id

The case classifier of the event log. A character vector containing variable names of length 1 or more.

activity_id

The activity classifier of the event log. A character vector containing variable names of length 1 or more.

activity_instance_id

The activity instance classifier of the event log.

lifecycle_id

The life cycle classifier of the event log.

timestamp

The timestamp of the event log. Should refer to a Date or POSIXct field.

resource_id

The resource identifier of the event log. A character vector containing variable names of length 1 or more.

order

Configure how to handle sort events with equal timestamps: auto will use the order in the original data, alphabetical will sort the activity labels by alphabet, sorted will assume that the data frame is already correctly sorted and has a column '.order', providing a column name will use this column for ordering (can be numeric of character). The latter will never overrule timestamp orderings.

validate

When TRUE some basic checks are run on the contents of the event log such as that activity instances are not connected to more than one case or activity. Using FALSE improves the performance by skipping those checks.

Examples

if (FALSE) {
data <- data.frame(case = rep("A",5),
activity_id = c("A","B","C","D","E"),
activity_instance_id = 1:5,
lifecycle_id = rep("complete",5),
timestamp = 1:5,
resource = rep("resource 1", 5))
eventlog(data,case_id = "case",
activity_id = "activity_id",
activity_instance_id = "activity_instance_id",
lifecycle_id = "lifecycle_id",
timestamp = "timestamp",
resource_id = "resource")
}
