I am doing a three way repeated measures ANOVA (2*2*2) with both R and SPSS and I got totally different results. I did GLM-repeated measures with 3 levels in SPSS and got two significant main effects, and I use the following code in R (condition, amount and delay are three within subject factors, but nothing is significant.

model<-aov(mean~condition*amount*delay+Error(ID/(condition*amount*delay)),data)

Can anyone explain the reason and am I using the right code in R?
