Dear all,
I'm a beginner of R and I need to carry out some three-way mixed ANOVAs.
Following examples at http://personality-project.org/r/r.anova.html, I
managed to get the ANOVA part, but I don't know how can I check data
normality and homogeneity of variance in R (since they're the required
assumptions of ANOVA analysis).
Are there any special command/packages? Could anyone give me some
pointers/examples?
Best regards,
Haiyang
