How to get Greenhouse-Geisser epsilons from anova?

Dear John,
thank you for the kind offer!
Sorry, I just made a mistake anywhere I can not trace back, now it works 
as you described it. Thank you again!

Dear Peter,
thank you for the information, I did not know about the quotation marks. 
It indeed works using "G-G Pr"!
The SPSS and R output for the epsilons differ exactly by N/(N-(k-1)). So 
I think it must be the mentioned bug.

I wish you merry christmas!
