Those currently undocumented and internally used functions are aliased to this help file. Ditto for some classes.
Each objects/methods/classes may or may not have its own individual value. These will be documented over time.

In the VGAM package there are currently many objects/methods/classes which are currently internal and/or undocumented. The help file suppresses the warnings when the package is 'CHECK'ed.
