[R] ANOVA between & within variance

[Gregor Rolshausen]

hi,
is there an option to calculate the 'within' & 'between' group variances 
for a simple ANOVA (aov) model (2 groups, 1 trait, normally distr.) ?
or do I have to calculate them from the Sum Sq ?

thanks for your time and greetings,

gregor
