"IndependenceProblem"Objects of class "IndependenceProblem" represent the data structure
  corresponding to an independence problem.
Objects can be created by calls of the form
     new("IndependenceProblem", x, y, block = NULL, weights = NULL, ...)where x and y are data frames containing the variables
  \(\mathbf{X}\) and \(\mathbf{Y}\), respectively, block is an
  optional factor representing the block structure \(b\) and weights is
  an optional integer vector corresponding to the case weights \(w\).
x:Object of class "data.frame".  The variables x.
y:Object of class "data.frame".  The variables y.
block:Object of class "factor".  The block structure.
weights:Object of class "numeric".  The case weights.
