Hello,

I am randomly generating values and then using an ANOVA table to find the
mean square value. I would like to form a loop that extracts the mean square
value from ANOVA in each iteration. Below is an example of what I am doing.

a<-rnorm(10)
b<-factor(c(1,1,2,2,3,3,4,4,5,5))
c<-factor(c(1,2,1,2,1,2,1,2,1,2))

mylm<-lm(a~b+c)
anova(mylm)

Since I would like to use a loop to generate this several times it would be
helpful to know how to extract the mean square value from ANOVA.

Thanks
