I'd like to know how to obtain a table of anova of a 3^2 desing with
linear and cuadratic sum of squares because if I use "aov", this
comand only bring me the linear sum of squares:
> A<-rep(c(rep(-1,3),rep(0,3),rep(1,3)),2)
> B<-rep(rep(c(-1,0,1),3),2)
>
y<-c(1.5,1.4,0.8,3.5,2.9,1.8,4,3.8,2.7,1.2,1.3,1.2,3.2,2.5,2,4.2,3.4,3
)
> anova(aov(y~(A*B)))
Analysis of Variance Table
Response: y

Thanks a lot ,
