-Some speculation about predictors vs. response variables (open to suggestion/comment/disagreement here)
-Included some plots I made to try and start thinking about relationships in the data (but not use regression yet)

Merge branch 'master' of github.com:mmallek/finalproject

Hopefully nothing gets overwritten through this!
Updated figure in final section

I figured out captions! See my code for details.

Also I have to comment out the \SweaveOpts thing for it to run but I guess until we solve it we'll have to go back and forth on this. I'm guessing one of us is missing something on our computer which, once installed, will solve the problem.
