Details

From version 1.9 of this package on, class "AbscontDistribution" has an extra slot gaps. As the addition of new slots will probably happen again in the future development of our packages, we provide the following two help functions isOldVersion and conv2NewVersion to check whether the object was generated by an older version of this package and to convert such an object to the new format, respectively. Also, the intermediate class "LatticeDistribution" is introduced at version 1.9 so that all subclasses of "DiscreteDistribution" like "Binom", "Nbinom" etc, now have an extra slot lattice. conv2NewVersion takes this up and provides a particular method for signature "LatticeDistribution" which fills slot lattice accordingly.
