How to include multiple random effects in a 'lme' function? For example, I want to set up 'days' and 'subject' as my random effects,
library(nlme) fm <- lme(trait~time+money, random=~days|subject, data=example) However, if I have the following SAS code: ---------------------------------------------- proc mixed data=example; class time money; model trait=time money time*money/noint s; random days/sub=subject; random int/sub=pedigreeID; title 'random slope model with family effects'; run; -------------------------------------------- In this SAS code, it has multiple random effects, how can I convert this SAS code to R code? library(nlme) fm <- lme(trait~time+money, random=list(???????????), data=example) How should I fill up the list()? thank you very much, Karena -- View this message in context: http://r.789695.n4.nabble.com/How-to-include-multiple-random-effects-in-lme-function-tp3598339p3598339.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.
