absent: Check if an activity is absent from a case

In gertjanssenswillen/processcheckR: Rule-Based Conformance Checking of Business Process Event Data

Description

The 'absent' rule can be used to check whether an activity is absent in a case or not. The 'n' parameter can be configured to create a different level of _absence_. When n = 1, an activity is not allowed to occur even a single time. The maximum number of times it is allowed to occur is 'n-1'.

Usage

absent(activity, n = 1)

Arguments

activity	The activity to check. Character vector of length one.
n	n-1 is the allowed number of occurences of the activity. E.g. n = 1 means the activity should be absent, n = 2 means it is allowed to occur once.
