>Hi, 
>I have a two-way anova with unequal cell numbers that I want to analyze. 
>The problem is I don't have individual observations of the data.
>I only have the sufficient statistics (mean, variance, # of observations) for each cell. 
>Is there any existing function in S-plus that would allow me to do aov() with the sufficient statistics?
