...gt;post effect when deciding whether there was a Treatment (noise) effect. Unfortunately, whenever, I put the Group factor in the Error term (to take into account subj:Group as a random effect), I get a singular result: (see the data entry section below) > rt.aov <- aov(rt ~ Group*prepost + Error(subj/(prepost*Group)), data=rt.df) Warning message: Error() model is singular in: aov(rt ~ Group * prepost + Error(subj/(prepost * Group)), data = rt.df) plus, I'm not sure how to include the replicate factor ("rep") in my Error() term -- should it be somethi...

...arry along all other attributes not recognized by smbtar, you know streams and stuff. Does anyone have a good CLI for ntbackup.exe? Sorry I got carried away by this fascinating subject.
