Subject: [R] anova in unbalanced data

Hi all,

Say I have the following data:

a<-data.frame(col1=c(rep("a",5),rep("b",7)),col2=runif(12))

a_aov<-aov(a$col2~a$col1)

summary(aov)


Note that there are 5 observations for a and 7 for b, thus is
unbalanced. What would be the correct way of doing anova for this set?


Thanks,

Sachin
