>This is suspicious : Spar_loc doesn't appear in your statement... Yes Spar_loc should look suspicious. I posted the real error messages but hid the variable names in the model. Spar_loc is the original form of S. >The precedence of modelling operators is not very clear (and does not >seem to be formally defined in the "standard" documentation...). In >doubt, use parentheses. >So try ...+(1|(S:A)/H), just in case.. This did not work. However I did discover something that does: AAT<- lmer(Y ~ S + A + (1|H %in% S:A), data=AT, REML=TRUE) Not sure why this worked. I read that it is an alternate way of specifying nesting. This runs without error. ______________________________________________ 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. -- View this message in context: http://www.nabble.com/Help-with-lme4-model-specification-tp23415908p23428678.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.
