Hi Dear Dr bolker.
Hope you are in good health. I amMeysam Tasallizadeh, a MSc. student in 
statistics at Tarbiat Modares University, Tehran, Iran. I plan to work on 
longitudinal data in my thesis.
I want to predict a linear mixed model with predict function that is below:

Error in (function (x, n)  : new levels detected in newdata

full.data is dataframe that the has dimension 3600x6 and f1 is beloow:
# lme fit.

I would highly appreciate it if you consider my question in error in predict 
linear mixed model.
