Dear R members,
I tried to fit an lme model and to use the glht function of multcomp.
However, the glht function gives me some errors when using

The glht error makes sense as glht needs factor levels and the model
works fine without weights=. Does anyone know a solution

The effect of habitat type on bee species number was tested using a glmer model

Dear R community
It is possible to adjust the legend in combined ggplots using ggarrange with
be positions top, bottom, left and right.
My question: Is there a function to change the position of the legend to
topright or bottomleft? Right and top etc are in the middle of the axis.
Kind regards

Could you supply us with a MWE (minimal working example)of what you have so far?
change the angel of the x-axis. However, I was able to change
the first x-axis (BB...), but not the second one (Voegel). Maybe this
would solve the problem.
- If not, is there another possibility to fix the number of subplots per
line?
