PCMListParameterizations: Specify the parameterizations for each parameter of a model

In PCMBase: Simulation and Likelihood Calculation of Phylogenetic Comparative Models

Specify the parameterizations for each parameter of a model

Description

These are S3 generics. 'PCMListParameterizations' should return all possible parametrizations for the class of 'model'. 'PCMListDefaultParameterizations' is a handy way to specify a subset of all parametrizations. 'PCMListDefaultParameterizations' should be used to avoid generating too many model parametrizations which occupy space in the R-global environment while they are not used (see PCMGenerateParameterizations). It is mandatory to implement a specification for 'PCMListParameterizations' for each newly defined class of models. 'PCMListDefaultParameterizations' has a default implementation that calls 'PCMListParameterizations' and returns the first parametrization for each parameter. Hence, implementing a method for 'PCMListDefaultParameterizations' for a newly defined model type is optional.

Usage

PCMListParameterizations(model, ...)

PCMListDefaultParameterizations(model, ...)

Arguments

model	a PCM.
...	additional arguments used by implementing methods.

Value

a named list with list elements corresponding to each parameter in model. Each list element is a list of character vectors, specifying the possible S3 class attributes for the parameter in question. For an example, type 'PCMListParameterizations.BM' to see the possible parameterizations for the BM model.
