Hallo thanks a lot for the answer, I found the Levene test in the car package.
I already tried to compute my Mauchly.test the same way as in the example(SSD) matrix <- lm(data) mauchly.test(matrix,X=~1) I was just unsure about it because with that I get a different result than when I do the Mauchly test with SPSS... hm thanks again, Tanja > Tanja Seifried <[EMAIL PROTECTED]> writes: > > > Hallo! > > > > > > I just started working with R to do the statistical analyses for my diploma > > thesis. > > I got two sets of data. > > Both contain repeated measures. > > One has only one within-subject factor with four levels. > > The other has one within-subject factor with two levels and one > > between-factor with two levels. > > > > I want to compute a Mauchly test for both sets and a Levene test for the > > second set. > > > > I couldn't find the LEvene test in R.
