How to read ANOVA output
Hi folks,
Where can I find document re "how to read anova output"? Google found many of
them. But seemingly non of them can explain to me following output:-
> tabA = c(5.67, 5.67, 5.55, 5.57)
> tabB = c(5.75, 5.47, 5.43, 5.45)
> tabC = c(4.74, 4.45, 4.65, 4.94)
> tabs = data.frame(tabA, tabB, tabC)
> tablets = stack(tabs)
> anova(lm(values ~ ind, data = tablets))
