distrMod (version 2.0.1)

InternalClassUnions: Class unions in 'distrMod'

Description

Class unions in package distrMod defined for internal purposes; these are OptionalNumeric, OptionalMatrix, MatrixorFunction, ShowDetails

Objects from the Class

All of these classes are virtual: No objects may be created from them.

Details

These classes are used internally to make available methods or to allow slots of classes to be filled with varying types. In particular

• "OptionalNumeric"

{may contain objects of class "numeric" or "NULL"; it is used e.g. for slot nuisance of class "ParamFamParameter", as it may or may not be present but if so it has to be numeric.} "OptionalNumericOrMatrix"{may contain objects of class "OptionalNumeric" or "matrix"; it is used e.g. for slot asvar of class "Estimate", as it may or may not be present but if so it has to be a number (numeric) or a matrix.} "MatrixorFunction"{may contain objects of class "OptionalFunction" or "matrix"; it is used e.g. for slot trafo of class "ParamFamParameter", as it may or may not be present and if it is present, it has to either be a function or a matrix, see link{trafo-methods}.} "ShowDetails"{may contain objects of class "Estimate", "MCEstimate", "Confint", "PosSemDefSymmMatrix" "ParamFamily", or "ParamFamParameter"; used to provide sort of a ``show with extra arguments'', in form of a common print method for these S4 classes, which essentially just temporarily sets the global options according to the optional arguments digits and show.details, calls show and then re-sets the options to their global settings.} "L2LocationScaleUnion"{is a proper, but virtual in-between class between class "L2GroupParamFamily" and "L2LocationFamily", "L2ScaleFamily", and "L2LocationScaleFamily"; in addition to class "L2GroupParamFamily" it has a slot locscalename (with corresponding accessor and replacement method) to capture the fact that location and scale parameter may carry names other than "loc" resp. "scale"; used to provide a common class for (parts of) methods modifyModel locscalename and locscalename<-.}
