cmatB.AB {daMA}R Documentation

Contrast matrix describing the experimental questions

Description

This matrix of numerical constants describes the experimental question, say p. 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. the first line of the matrix cmatB.AB describes the main effect B.
