Why aov() with Error() gives three strata?
...his can be interpreted using random effects as above, with variances of each component proportional to the successive differences. (All assuming that you have a balanced data layout, otherwise aov() is just the wrong tool.) -pd > On 28 Dec 2017, at 19:36 , Jorge Fernando Saraiva de Menezes <jorgefernandosaraiva at gmail.com> wrote: > > Bert, thanks for the reply but I feel that my question is less about > statistics and more about R interface.

Why aov() with Error() gives three strata?
Dear list users, I am trying to learn Repeated measures ANOVA using the aov() interface, but I'm struggling to understand its output. According to tutorials on the web, formula for a repeated measures design is: aov(Y ~ IV+ Error(SUBJECT/IV) ) This formula does work but it returns three strata (Error:SUBJECT, Error: SUBJECT:IV, Error: Within), when I would expect two strata (Within and

rep() fails at times=0.29*100
Dear list, I have found an unusual behavior and would like to check if it is a possible bug, and if updating R would fix it. I am not sure if should post it in this mail list but I don't where is R bug tracker. The only mention I found that might relate to this is "If times is a computed quantity it is prudent to add a small fuzz." in rep() help, but not sure if it is related to
