Arguments

design	An object of class msreve_design.
pairs	Optional two-column matrix or list of character vectors specifying pairs of contrast column names. Default NULL uses all pairwise combinations.
orthogonalize	Logical; if TRUE (default) the expanded contrast matrix is passed through orthogonalize_contrasts.
