Hi Steve,
You need to explicitly print the ggplot object:

Hello all.
I'm working on a PhD thesis analyzing reproducibility/repeatability of a
nuclear medicine examination. I have two sets of data (50 patients each)
and 3 observers. In each case (patient), two variables are evaluated,
first with a range of 0..100 and second 1..3. Each case is also
Hello all,
I am using lme4 to fit some mixed logistic regressions. I need to
impose an identification constraint of the following form:
