Description Usage Arguments Value Author(s) See Also Examples

Construct and randomize a regular factorial design.

regular.design(factors = NULL, nlevels = NULL, block = NULL,
   ordered = NULL, hierarchy = NULL, model = NULL, estimate = NULL,
   listofmodels = NULL, resolution = NULL, nunits = NULL,
   base = NULL, randomize = NULL, randomsearch = FALSE,
   output = "planordesign", verbose = FALSE, ...)

`factors`	an object of class `designfactors`, typically an output from `planor.factors`). Otherwise the arguments `factors`, `nlevels`, `ordered`, `hierarchy` follow the syntax of `planor.factors`.
`nlevels`	see `planor.factors`. Ignored if `factors` is of class `designfactors`.
`block`	see `planor.factors`. Ignored if `factors` is of class `designfactors`.
`ordered`	see `planor.factors`. Ignored if `factors` is of class `designfactors`.
`hierarchy`	see `planor.factors`. Ignored if `factors` is of class `designfactors`.
`model`	a list of model-estimate pairs of formulae, typically an output from `planor.model`. Otherwise the arguments `model`, `estimate`, `listofmodels` and `resolution` follow the syntax of `planor.model`.
`estimate`	see `planor.model`. Ignored if `model` is a list.
`listofmodels`	see `planor.model`. Ignored if `model` is a list.
`resolution`	see `planor.model`. Ignored if `model` is a list. When set and there is no hierarchy, a faster algorithm is used which exploits the symmetries.
`nunits`	see `planor.designkey`.
`base`	see `planor.designkey`.
`randomize`	an optional formula to randomize the design.
`randomsearch`	see `planor.designkey`.
`output`	a string to specify the class of the output value: either a `data.frame` or a `planordesign` object.
`verbose`	a `logical` to set to `TRUE` for verbose display.
`...`	additional arguments, in particular those related to randomization

An object of class data.frame or planordesign, depending on the output argument.
