52 Weeks of Data Science - Week 4

This past week was spent primarily solving Rosalind problems and getting more familiar with R. I’ve found that I need to do some reviewing of Math/Statistics. I’m feeling a bit rusty in that regard, and it’s holding me back on some of these problems.

Some notes

I figured it would be good to also note some common patterns/code that I’ve been using to solve these problems.
