[R] aov() and NaN

[Jan Malte Wiener]

hi,
another anova question !!
how does aov() treat missing values ?

since it might depend on my experimental design:
i have a within subject design with two factors ...

i use aov() like this:

aov(performance~type*block+Error(subj/(type+block)),data=anovaData)

now it might happen that i have a couple of NaN data points in my result 
dataFrame.
how can i know/control how aov() is treating those missing values ?

greetinx jan
