I would like to buy a basic statistics book (experimental design,
sampling, ANOVA, regression, etc.) with examples in R. Or download it
in PDF or html format.
I went to the CRAN contributed documentation, but there were only R
textbooks, that is, textbooks where R is the focus, not the
.
Is it possible to use lmer() without fixed effects?
Anything would help.

I don't have a grouping variable. And yes, persons can be an important

Harold, I have tried to adapt your syntax and got some problems. Some

On this one, I have tried to use 1 as a grouping variable. As I understood
from Bates (2005), grouping variables are like nested design, which

format, instead of scientific format?

I have tried the following syntax:

with different fixed effects; in that case, you
should use method = ML, as explained in Pinheiro and Bates (2000).
Hope this helps.

Thank you for your reply
