This is more a statistic thing than an R question.

I have length measurements of organisms which I want to use for an two-way ANOVA( fixed factors)
The problem is that I have different number of replicates for each combination of factors.

What are the strengths and weakness of these approach when I applly aov function in R.
The help file states  : 
     'aov' is designed for balanced designs, and the results can be
     hard to interpret without balance.....

Thank you
