Description Usage Arguments Value Note Author(s) Examples

Harmonize the factors originating from a list of factors, a list of models, and a list of basic factors (this function is essentially for internal use).

An object of class `designfactors`

very
similar to `factors`

, but with two additional logical columns in
slots `fact.info`

and `pseudo.info`

:

- `model`

(TRUE for the factors present in at least one model formula),

- `basic`

(TRUE for the basic factors).

This function is called at the start of the design search. It is
essentially a check that the factors in all three arguments are
coherent, even though it performs some additional tasks. The function
stops if it detects a model or basic factor that is absent from
`factors`

. This is because the number of levels of such a factor is
unknown and so the design search cannot proceed. Besides, the function
eliminates the factors that do appear neither in `model`

nor in
`base`

and it reorders the factors by putting first the basic
ones.
