Your example is not easily reproducible.
The REBayes requires Rmosek which requires a system command MOSEK.
Please try again with an example using data in base R.
Meanwhile, my guess is that you will need to do something like
explicitly specifying xlim and ylim so all panels have the same
limits.

I am trying to do some comparisons of density estimators using lattice.
The code below attempts to plot the same histogram in each panel and
then overplots a kernel estimate with different bandwidths. Finding
packet.number() was a bit arduous, but seems to do what I want. My
concern now is that close examination of the 4 histograms reveals that
they are different even though they use the same data, and use the
same binning. Can someone explain this, or better yet suggest a fix?
Admittedly, the kernel estimates are rather silly, they are just standing
in for something else that I would like to think is less silly.
Many thanks,
Roger
