Hi all,
I'm doing a 3-way ANOVA like this:
summary(aov(formula('FP ~ (lum * obj * man)3 - Error(vp/(lum * obj *
man)3)'),data=dataf))
But in the output I only get 1- and 2-way effects, like this one:
Error: vp:obj:man
Df Sum Sq Mean Sq F value Pr(>F)
obj:man 1 1.5291e-34 1.5291e-34 5.7011 0.0542 .
Residuals 6 1.6093e-34 2.6822e-35
---
Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1
(And a warning that the Error() model is singular.)
What am I doing wrong so that I don't get the 3-way interactions I want
to look at?
Thank you!
Marius.
