doNothing: An action function that does nothing

In TrialSimulator: Clinical Trial Simulator

An action function that does nothing

Description

This is an action function that does nothing when the corresponding milestone is triggered. When the listener is monitoring a trial and determining the time to trigger a milestone, data is automatically locked with other necessary data manipulation being executed. If the users have no intent to modify the trial adaptively at the milestone, e.g., adding (add_arms()) or removing (remove_arms()) arm(s), changing sampling ratio(s) (update_sample_ratio()), modifying trial duration, carrying out statistical testing, or saving intermediate results (save()), then this function can be used to set the argument action when creating a new milestone. Note that the triggering time of a milestone with action = doNothing is still recorded in output automatically.

Usage

doNothing(trial, milestone_name)

Arguments

trial	a Trial object.
milestone_name	character. Name of milestone being triggered.

Value

This function returns NULL. Actually, nothing is done in this function.
