Although the main method is for class "lm", aliasSlip Men's Shoes Audtee Brown Walking Shoes Outdoor Leisure Canvas Loafers on Driving Cloth f5AFA is most useful for experimental designs and so is used with fits from aov. Complete aliasing refers to effects in linear models that cannot be estimated independently of the terms which occur earlier in the model and so have their coefficients omitted from the fit. Partial aliasing refers to effects that can be estimated less precisely because of correlations induced by the design.

The aliasing pattern may depend on the contrasts in use: Helmert contrasts are probably most useful.

The defaults are different from those in S.
