Optimisation and NaN Errors using clm() and clmm()
...1 observations deleted due to missingness)
Warning message:

I have tried a number of different approaches, each has its own
problems. I have fixed these using various suggestions from online
forums (eg
https://stat.ethz.ch/pipermail/r-sig-mixed-models/2011q1/015328.html,
https://stat.ethz.ch/pipermail/r-sig-mixed-models/2011q2/016165.html)
and this is as good as I can get it.
After the first stage (generating the model set with glmulti) I tested

limits the resolution to 1024x768. I tried to force the use of intel driver
by writing a xorg.cof file, but then X doesn't start at all.
I updated libdrm and xorg-x11-drv-intel from
