any r tutors available here? I need someone to look at my code

We're all tutors here. See FAQ: What's a reproducible example (`reprex`) and how do I do one? and post the code and a list of where you're stuck, confused or just don't understand the results. After a while you'll find what many of us do, which it's a lot easier to spot errors in someone else's code than your own. Besides, other people probably have similar questions, so your's can help build the knowledge base here.
