Hi,
 
I have an unbalanced dataset on which I would like to perform a one-way anova test using R (aov). According to Wannacott and Wannacott (1990) p. 333, one-way anova with unbalanced data is possible with a few modifications in the anova-calculations. The modified anova calculations should take into account different sample sizes and a modified definition of the average. I was wondering if the aov-function in R is suitable for one-way anova on unbalanced data.
 
Thanks,
 
Ake Nauta
