I'm trying to set up a mixed model to solve using lme. It will have 3 fixed effects, two random effects and two interaction terms.
I've been reading Pinheiro's and Bates's book on the nmle library, but find the part about display functions to be unclear. When creating a groupedData object from a data.frame, you need to enter a function of the form: response ~primary|grouping Does this display function serve any purpose later on when specifying the model in the call to lme? If so, how would I include more terms in primary or grouping (I tried primary1+primary2+... as per one post in the archives, but it didn't work). If not, is it just for purposes of displaying the data? Thanks much, Scott Rifkin ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
