Nick Cox thank you for replying.

This is what I see

I would like to create a variable that merges the results of neuro5e_8 neuro5e_7 neuro5e_6 neuro5e_5 neuro5e_4 neuro5e_3. This way, I will be able to draw a mixed model in the next steps.

Sorry, but as yet that still isn't clear to me. Perhaps you need a reshape long.
