...ons that we are making change in the individual groups over time. According to my very limited statistics training that means that I would have to do a two-way anova with repeated measures because the same subjects are observed on the different weeks. Now in R I can do something like this: MyData$fWeek <- factor(MyData$Week) #Convert week to factor m1 <- aov(Readout ~ Group*fWeek + Error(Subj/fWeek), data=MyData) My first naive question is: Is the Error(...) term correct for the design that I describe? I am not quite sure if I understand the syntax correctly. In any case, it actually seem...

Hi Hadley: Not sure if you received my email, so I am resending it again. I have dealt with this before and I can't remember how it got resolved. It is too much data to reproduce the example below(49.000 records) but all I am after is trying to get the x axis breaks. I want my x axis to go from 27 to 51 and 1 to 25 by 2. I am trying to concatenate the breaks but it sorts the seq() in ascending
