I'd like to apply a 2^k factorial design with k=10 parameters.
Obviously this results in a quite long term for the model equation due
to the high number of combinations of parameters.
How can I specify the equation for the linear model (lm) without
writing all combinations explicitly down by hand? Does a R command
exist for this problematic?
Use expand.formula() in the AlgDesign package.
