Worksheet 1

The questions here have solutions attached. Follow the solutions to see what to do, if you cannot otherwise guess.

It is worth your while to work through these problems, and the ones in future tutorial worksheets, because they will get you used to how R operates, and gain you some comfort in coding simple things. If you do not work through these problems now, any issues that you could have dealt with this week (with help available) come back to bite you when you will have an assignment due. This is stress you would do well to be without.
