- Hello, and welcome to Code Clinic for R. My name is Mark Niemann-Ross and I'm excited to show you my solutions for the challenges proposed to the Code Clinic authors. In this series, we'll explore creative and efficient ways to use R to solve a range of problems. I'll describe some of the unique features of this language and show you some tips on how to make your code run faster and be more reliable, as well as pointers on making it more readable.
So, let's get started with Code Clinic for R.
