Function cross.design
returns a simple data frame without design
information, if design1
is not of class design
.
Otherwise, the value is a data frame of class design
with type “crossed” and the following extraordinary elements:
cross.nrunsvector of run numbers of individual designs
cross.nfactorsvector of numbers of factors of individual designs
cross.typesvector of types of individual designs
cross.randomizevector of logicals (randomized or not) of individual desigs
cross.seedvector of seeds of individual designs
cross.replicationsvector of numbers of replications of individual designs
cross.repeat.onlyvector of logicals (repeat.only or not) of individual designs
cross.maplist with the map vectors for component designs of type FrF2.estimable
cross.selected.columnsNULL
(if no oa
type design) or list of column vectors for each design
cross.nlevelslist with the nlevels
vectors for those component designs that have them
The standard elements are as usual, with randomize and seed referring to
the randomization within function cross.design itself (previous randomizations are shown
under cross.randomize and cross.seed).
The nlevels element of design.info is available only if it is
available for all designs that have been crossed (otherwise refer to the element cross.nlevels.
The creator element of the design.info attribute consists is a 2-element list
containing
the list original of all the original creators and
the element modify that contains the call to cross.design.
If present, the clear, ncube, ncenter, residual.df,
origin, comment, generating.oa elements of design.info are vector-valued.
If present, the generators element of design.info is a list of character vectors.
If present, the aliased and catlg.entry elements of design.info are lists of lists.
