keyring-class {planor} | R Documentation |
An S4 class to represent a list of design-key matrices which are associated with the same prime and which represent alternative solutions to the same design specifications.
Each component of the structure
returned by planor.designkey
is a keyring
object when the
case is not recursive.
a list of keymatrix
objects.
a prime number.
a list containing a vector of row names and a vector of column names. The names are the same for all key matrices.
a dataframe containing information on the
pseudofactors associated with the key matrices. See the
description of the class designfactors

Each key matrix in a keyring
object is a possible solution
to the same factors, model and estimate specifications, with respect
to the same prime number. An object of class
listofkeyrings
is a list of keyring
objects associated with the different primes involved in a given
factorial design problem.
