Edit to this question:
This is a very simple question and I apologise for having over-complicated it. Below is what I should have asked. Any advice would be a big help, please!
- I have a panel of 2 x 4 boxplots showing the chemical concentrations in samples from two site-types, A and B.
- Since I have a total of eight boxplots (created using the cowplot function), I don't want 'site type' underneath each of all eight plots.
- I just want to have 'site type' on the x-axis of the bottom four plots. How is this done please?
Thank you very much in advance for advice!
Cheers
Mike
I apologise for not producing an example. I can produce one if necessary but I think you'll agree it's quite a basic question
