WebDetails. This function expresses contrasts between a set of parameters as a numeric matrix. The parameters are usually the coefficients from a linear model fit, so the matrix specifies which comparisons between the coefficients are to be extracted from the fit. The output from this function is usually used as input to contrasts.fit .
