Stephanie Worobey week 20, 21, 22

I've been working on primarily the same project throughout this time. Trying to find the total number of discrepancies in smoking status was pretty tricky, but I was able to find this number after doing some research and much perseverence (yay!). I also took some time to learn how to use knitr, a package in R that allows me to create html documents so I can easily share my code and results and reduce risk of error. As a group we also submitted a proposal  to the undergraduate research conference at our university.
