Analysis of variance of linear models fitted from a formula. Equivalent to R's anova(). With one fit, the table of sequential (type I) sums
of squares, equivalent to R's anova(fit): one row per term (the intercept left out), in the order of the model,
and Residuals. With several fits, the comparison of the models in the order given, equivalent to R's
anova(fit1, fit2, ...): columns Res.Df, RSS, Df, Sum of Sq, F, Pr(>F), the F tests scaled by the
residual mean square of the model with the fewest residual degrees of freedom.
