Machine Learning with R: An Irresponsibly Fast Tutorial

As I said in Becoming a data hacker, R is an awesome programming language for data analysts, especially for people just getting started. In this post, I will give you a super quick, very practical, theory-free, hands-on intro to writing a simple classification model in R, using the caret package. If you want to skip the tutorial, you can find the R code here. Quick note: if the code examples look weird for you on mobile, give it a try on a desktop (you can't do the tutorial on your phone, anyway!). One of the biggest barriers to learning for budding data scientists is that there are so many different R packages for machine learning.
