Subject: AOV with repeated measures
Dear R user,
I have a question on using R to analyze data with repeated measurements. I
have 2 species with several strains (12) per species, each of which has
been measured twice with for a given trait. No particular covariance, just
two measures. Now I want to analyze the data with an ANOVA (aov)
considering these repeated measures to get the MSq and SSq for the species
and strain level. I would like to know how to write the ANOVA model in R. I
have done the following:
aov(trait ~ species + strain/replicate)
Is it accurate?
Thanks a lot,
Christian
