Could someone or Richard explain to me what he meant by "This also shows a singular Error(). We look at the data and see that plot is identical to the three-way veget:fruit:block interaction." It seems to me that I just needed to recoded the plots, in order to get rid of the Error message. If that is true, then why I can't go back to the original model proposed by Richard track.aov <- aov(mice ~ coon + block * veget * fruit * time - block:veget:fruit:time + Error(block/Plot), data = track)
and calculate F values myself? Thank you very much for the feedback. -- View this message in context: http://www.nabble.com/ANCOVA-with-defined-error-terms-tp25055311p25147303.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
