[R] How to get the full (overparametrized) model matrix
Dear all, If I use model.matrix on a formula including factors, then "superflous" columns of the model matrix are removed (or rather estimability constraints are imposed). Is there a way of getting the "full" model matrix, i.e. without removing redundant columns?
