Homework 2

Due in class, Wednesday 9 Sep.

Revise last week's homework based on what you have learned in class, discussion with your colleagues, and my feedback (if I get it back to you in time). Include revised versions of two plots and one new plot that shows off your data cleaning skills.

You do not need to show the process by which you reached each plot. However, I would encourage you to include the code for some plots that were informative, but didn't make the final cut.

You should work semi-independently on the homeworks: every group member should explore something different, with the idea of picking the most interesting findings for the project.

Like last week, your report should be written in Latex and should include an appendix that contains all of the code necessary to reproduce the graphics. The code should be formatted according to the style guide, paying close attention to the grading schedule below.

Grading

This assignment will be graded out of 15 according to the homework rubric. One point will be deducted for each of the following style violations:

Incorrect spacing around commas, parentheses, operators or comments.
Lines that are wider than 80 columns so that they are either wrapped inappropriately, or cut off by the side of the page.
Failure to include descriptive comments which tell me what you are trying to achieve (not how you are achieving it).
If you create new variables, using names that do not accurately express the content of the variable.

Note that you can lose 4 out of a total of 15 points from style violations. Be careful! I emphasise these points because they are so important for the long term maintainbility of your code, and because the more easily I can understand your code, the better the grade you will get.
