When should I use aov() and when anova()?
<p>I have referred to much of online literature but it is increasing my confusion. Much of the discussion is too technical with terms unbalanced designs and I, II or III factor ANOVA and everything.</p>

<p>I only know that <code>aov()</code> uses <code>lm()</code> internally and is useful for data with factors. Whereas <code>anova()</code> can be used for different models on same dataset.
Is my understanding correct?</p>
