singular).
What you can do is try something like this:
summary(aov(formula('FP ~ (lum + obj + man)^2 - Error(vp/(lum + obj +
man)^2)),data=dataf))
(notice the use of + and ^)
This is something your data might permit (assumi
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 0.05
Marius think you wanted to do a new post and not reply to mine :P
