Dear R-help, Does anyone have a function that I could use to determine power for testing significance of an interaction term in a 2-way ANOVA. The model I am considering has 2 levels in each factor. I would like to be able to input sample size (equal in all groups), MSE, means for the 4 groups, and then get power for the 2 main effects and interaction term. It would also be nice to enter the desired power for the interaction effect, and then get sample size for the 4 groups. Any help or guidance would be greatly appreciated.
Best wishes, -- Justin S. Rhodes Department of Psychology Beckman Institute Neuroscience Program, Institute for Genomic Biology University of Illinois 405 N.
