Declare the factorial terms that must be considered as nonnegligible and the factorial terms that must be estimable when the experiment will be analysed.

main model formula. It contains all the nonnegligible factorial terms. 
estimate 
optional formula specifying the factorial terms to
estimate. If missing, it is considered that all factorial terms in

A list of c(model, estimate)
pairs, where model
and

are formulae.
The user can specify:
1/ either, model
or listofmodels
or both,
2/ or, resolution

, and possibly
listofmodels
.
When model

are both set, model

ignored.
The second case, — when resolution
and
factors
are set —, causes the automatic generation of the
main c(model, estimate)
pair. Assuming S
denotes the
additive formula including all factors,
 if resolution
is odd, the model formula is
~(S)^(resolution1)/2
,
 if resolution
is even, the model formula is
~(S)^(resolution/2)
and the estimate formula is
~(S)^(resolution/2)1
.

planor.model(model=~block + (A+B+C)^2, estimate=~(A+B+C)^2)
### Resolution: both calls to planor.model below are equivalent
planor.model(model=~(A+B+C+D)^2, estimate=~A+B+C+D)
myfactors < planor.factors(factors=c(LETTERS[1:4]), nlevels=rep(2,4))
planor.model(resolution=4, factors=myfactors)
### Complicated examples
planor.model(~A+B+C+D+A:B, ~A+B+C+D, listofmodels=list(c(~E+F,~E)))
planor.model(~A+B+C+D+A:B,~A+B+C+D, listofmodels=
list(c(~E+F,~E), ~G, ~H, c(~M+N,~N)))
