However, I get the following error when using the <predict> command:
Error in eval(expr, envir, enclos) : object 'size' not found
I'm not sure why I am getting this error. I have used the same commands on a similar dataset before and was able to produce the attached plot (plot.docx). I've also attached the data I've been using (final.csv).
Any pointers would be greatly appreciated!!

1. I will NOT analyse your data for you.
2. Your deadline is your problem.
