No. This list is not for doing homework, though I applaud your honesty in admitting it. Your instructor is being paid to teach you; that's who you should be consulting, rather than asking people on this list to help you cheat. Good luck, Sarah I have using the R tutorials and help options but it just is not helping me at all. I have some questions completed but these are the ones i need help on: > A.)
