[R] anova repeated measure

Dear R people, I'm new user of R and I'm trying to do a Anova with 3 different tests (intra subject), 6 times of measures (intra subject) and 3 groups (inter subject). I want to obtain an Huynh-Feldt epsilon on accuracy with: anova(lm(acc.t1~gr.dem),test=Spherical) for test 1 # gr.dem is my group

Hi R people, I'm trying to do a Anova with 3 different tests (intra subject), 6 times of measures (intra subject) and 3 groups (inter subject). I want to obtain an Huynh-Feldt epsilon on accuracy with anova(lm(acc.t1~gr.dem),test=Spherical) for test 1 # gr.dem is my group variable
