"cplm" class and its derived classes "cpglm", "cpglmm", "bcplm" and "zcpglm". Several primitive methods and statistical methods are created to facilitate the extraction of specific slots and further statistical analysis. "gini" is a class that stores the Gini indices and associated standard errors that could be used to perform model comparison involving the compound Poisson distribution. "NullNum", "NullList", "NullFunc" and "ListFrame" are virtual classes for c("NULL", "numeric"), c("NULL","list"), c("NULL","function") and c("list","data.frame"), respectively."cpglm" extends class "cplm ", directly.Class "cpglmm" extends class ", directly;
