Objects of class `"SymmetryProblem"`

represent the data structure
corresponding to a symmetry problem.

- Keywords
- classes

##### Objects from the Class

Objects can be created by calls of the form

new("SymmetryProblem", x, y, block = NULL, weights = NULL, \dots)

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 \(w\).

##### Slots

:Object of class

`"data.frame"`

. The variables`x`

.`y`

:Object of class
