function to convert matrix, data frame or object of class planordesign to class design (allowing use of convenience functions, particularly plotting with mosaic plots)
data2design(x, quantitative = rep(FALSE, ncol(x)), ...)
planor2design(x, ...)an object of class design with the type and
creator element of design.info given as external
or planor. For designs of type planor, the generators
element of the design.info
attribute contains the designkey from the original planor design.
an object of class data.frame, matrix
(function data2design) or planordesign
a logical vector, indicating which factors are quantitative;
defaults to all factors being qualitative
currently not used
Ulrike Groemping
For matrices and data frames, an unreplicated and unrandomized design is
assumed (not crucial, but the some entries of the design.info attribute
and the entire run.order attribute of the result will
be wrong otherwise). Per default, all factors are treated as qualitative and
thus made into factors, if they are not factors already.
Items of the S4 class planordesign are regular factorial designs
created by package planor (the designs itself is in the slot design).
Function planor2design transforms them into objects of the S3 class
design; currently, only the most basic information is included
(nunit and the factor information);
the design is assumed to be unrandomized and unreplicated.
