Extracting model predictions (@eta) from lmerMod objects #1

Closed andkov closed 7 years ago

andkov commented 10 years ago

Open repository Run "1.ISE-NLSY97-Religion.R" This will produce the data and run the first model, creating an lmer object. Now we want to extract the model predictions form in. In the "3.plotting lmer results in ggplot2.R" lines 21-26 are supposed to do that but throw an error Error in data.frame(model@flist, timec = model@X[, 2], YHat = model@eta) : no slot of name "X" for this object of class "lmerMod"

This is strange, because it used to work. Any thought what might be the matter?

Can you paste or link to the code? My first suspect with lme4 is making sure I made the variable a factor.

I think it's done/resolved. Reopen if not.
