Class representing multivariate distributions constructed using Sklar's theorem.
Objects are typically created by mvdc(), or
  can be created by calls of the form new("mvdc", ...).
copula:margins:Object of class "character",
      specifying the marginal distributions.
paramMargins:Object of class "list", whose
      each component is a list of named components, giving the parameter
      values of the marginal distributions. See mvdc.
marginsIdentical:Object of class "logical",
      that, if TRUE, restricts the marginal distributions to be
      identical, default is FALSE.
signature(x = "mvdc"): ...
signature(x = "mvdc"): the dimension of the
      distribution; this is the same as dim(x@copula).
signature(x = "mvdc"): ...
signature(object = "mvdc"): quite compactly display
      the content of the "mvdc" object.
