Something like , assuming the variables batches, operators, treatment, rep are factors and y is numeric, model <- aov(y ~ rep + batches + operators + treatment) or model <- aov(y ~ batches + operators + treatment) (which will give another parametrization of the same model) summary(model) Kjetil Halvorsen > I appreciate in advance. > > L. > > ______________________________________________ > [EMAIL PROTECTED] mailing list > https://www.stat.math.ethz.ch/mailman/listinfo/r-help ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
