Count the number of free parameters associated with a PCM or a PCM-parameter

PCMParamCount(
  o,
  countRegimeChanges = FALSE,
  countModelTypes = FALSE,
  offset = 0L,
  k = 1L,
  R = 1L,
  parentModel = NULL
)

Arguments

o	a PCM model object or a parameter of a PCM object
countRegimeChanges	logical indicating if regime changes should be counted. If TRUE, the default implementation would add `PCMNumRegimes(model) - 1`. Default FALSE.
countModelTypes	logical indicating whether the model type should be counted. If TRUE the default implementation will add +1 only if there are more than one modelTypes (`length(attr(model, "modelTypes", exact = TRUE)) > 1`), assuming that all regimes are regimes of the same model type (e.g. OU). The implementation for MRG models will add +1 for every regime if there are more than one modelTypes. Default FALSE.
offset	an integer denoting an offset count from which to start counting (internally used). Default: 0.
k	an integer denoting the number of modeled traits. Default: 1.
R	an integer denoting the number of regimes in the model. Default: 1.
parentModel	NULL or a PCM object. Default: NULL.
