Thanks for your help. How would I extract each of the 3 values in the vector
individually?
Thanks again

Hi:
It's easier to use an apply family function than a loop for this type
of problem, as illustrated below:
# Generate 30 random samples of size 10 from a standard
# normal distribution and put them into a matrix
u <- matrix(rnorm(300), ncol = 10)
a <- factor(rep(1:5, each = 2))
b <- factor(rep(1

If you are going to use R, it would pay you to learn a little bit about it.
Like, e.g., vector indexing.
In your example
anova(mylm)[["Mean Sq"]][3]
would g
