Global and S3 generic functions for manipulating model parameters. The parameters in a PCM are named objects with a class attribute specifying the main type and optional properties (tags).

S3 generic functions:

PCMParamCount()

Counting the number of actual numeric parameters (used, e.g. for calculating information scores, e.g. AIC);

PCMParamLoadOrStore(), PCMParamLoadOrStore()

Storing/loading a parameter to/from a numerical vector;

PCMParamLowerLimit(),PCMParamUpperLimit()

Specifying parameter upper and lower limits;

PCMParamRandomVecParams()

Generating a random parameter vector;

For all the above properties, check-functions are defined, e.g. `is.Local(o)`, `is.Global(o)`, `is.ScalarParameter(o)`, `is.VectorParameter`, etc.
