eventlog: Eventlog

Description

A function to instantiate an object of class eventlog by specifying a data.frame or tbl_df 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 tbl_df.

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

# NOT RUN {
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")
# }
