I think the easiest way is from calling anova() on your aov class object. For instance
y <- 1:10 x <- runif(10) my.aov <- aov(y ~ x) anova(my.aov)["Residuals", "Sum Sq"] anova(my.aov)["x", "Pr(>F)"] You can also extract these values from a call to summary(my.aov), but that output is a list (even for an ANOVA with a single error stratum), so you'd have to add [[1]] selecting the first (or if there were more than one whichever you wanted) element of the list. summary(my.aov)[[1]]["Residuals", "Sum Sq"] Cheers, Josh On Tue, Jul 13, 2010 at 7:35 AM, Luis Borda de Agua <lba...@gmail.com> wrote: > Hi, > > I have used the instruction aov in the following manner: > > res <- aov(qwe ~ asd) > > when I typed "res" I get: > _________ > Call: > aov(formula = qwe ~ asd) > > Terms: > asd Residuals > Sum of Squares 0.0708704 0.5255957 > Deg. of Freedom 1 8 > > Residual standard error: 0.2563191 > Estimated effects may be unbalanced > _________ > > I need to access the value of the Sum of Squares (i.e. I want another > variable to be equal to it, e.g myvar <- Sum.of.Squares) . > I tried names(res) to see which values are accessible, but I couldn't find > the Sum of Squares.
