cmat


This matrix of numerical constants describes the experimental question, $p$ say. Each experimental question is
described by a single contrast vector (a single row in cmat) or by a contrast matrix
(several rows in cmat). The ordering of the columns corresponds to that of the associated
design matrix X. Thus, typically the first two elements in a row of cmat are reserved for
for the two dyes. E.g. to compare the two dyes, we set (-1, 1, 0, ..., 0). 


datasets

This package contains functions for the efficient design
of factorial two-colour microarray experiments and for the
statistical analysis of factorial microarray data. Statistical
details are described in Bretz et al. (2003, submitted)
