[R] Why F value and Pr are not show in summary() of an aov() result?

[Peng Yu]

I have the following code. I'm wondering why summary() doesn't show F
value and Pr?

Rscript multi_factor.R

> b=4
> c=5
> d=6
> e=7
>
> A=1:a
> B=1:b
> C=1:c
> D=1:d
> E=1:e
>
> X=matrix(nr=a*b*c*d*e,nc=5)
> colnames(X)=LETTERS[1:5]
>
> for(i_a in 1:a-1) {
+   for(i_b in 1:b-1) {
+     for(i_c in 1:c-1) {
+       for(i_d in 1:d-1) {
+         for(i_e in 1:e-1) {
+           X[(((i_a * b + i_b) * c + i_c) * d + i_d) * e + i_e + 1, ]
= c(i_a+1, i_b+1, i_c+1, i_d+1, i_e+1)
+         }
+       }
+     }
+   }
+ }
