Programming Homework Help

Hello I have attached the zip file in this thread. I would like to know if you can give me a detailed explanation, step by step, illustrating how you completed this assignment. Basically, my professor would like to go over this assignment with every student to see if they understand. This was quite some time ago and I really need a detailed refresher

Note: TUTOR MUST HAVE R software in order to look over assignment. I have no way for changing the zip R files to a different format.
