Stop methods (e.g. "es.mean", "ks.mean", etc.) object, used only for backward compatibility
In older versions of twang, the 'ps' function specified the 'stop.method' in a different manner. This 'stop.methods' object is used to ensure backward compatibility; new twang users should not make use of it.
stop.methods
An object of class matrix (inherits from array) with 1 rows and 6 columns.
This is merely a vector with the names of the stopping rules.
