Can you explain what do you mean by "5 replicate tanks"? Doing a two way anova is very simple in R. You would need to fit a linear model (lm function).
Eg.: > model <- lm(y ~ male + female + male:female, data =) Regards, Indrajit ________________________________ From: Austin Paul <austi...@usc.edu> To: r-help@r-project.org Sent: Tuesday, September 27, 2011 6:13 AM Subject: [R] two-way anova help Hello, I am having some trouble coding a two-way anova due to replicated treatments. I have a factorial design with three male parents and three female parents. They were mated in all combinations and their babies were grown out and measured for size. 50 babies were measured for each of the 9 crosses. If I stopped here, I would have no troubles. But I also have 5 replicate tanks for each of the 9 crosses. My question is how to I code in the 5 replicate tanks per treatment?
