Help for a project

Actually, if you have the project up and running it sounds like you are fine unless the prof is being very picky about formatting or something.

You could post code and some sample data here and see if anyone has comments. See FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need. Just do dput(mydata) where mydata is your data. Copy the output and paste it here.
