8-) This is not my specialty, but could it be that you have an empty error
8-) stratum? I.e. if Subject:fac1:fac2 is the entire data set, then there
8-) is no DF for the residual error. (If so, try Error(Subject/(fac1+fac2)) )
I'm not sure what you mean with "the entire data set". I have one value for obs1 and one for obs2 for each combination of Subject, fac1 and fac2.
I tried your suggestion; got the same error message.
BTW: Would that not also cause problems in a regular anova, with aov?
