R is a language and environment for statistical computing and graphics.

R has a functional programming foundation, but facilitates procedural or object-oriented approaches.
R’s metaprogramming capabilities allow for magically succinct and concise functions.
R provides powerful tools for data manipulation, visualisation, modelling, and machine learning.
R has a diverse and welcoming community.
Every language has its own way of doing things. R is no different. Our mentors will help you learn to think like a R developer and how to write idiomatic code in R. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in R - they'll help you discover the things you don't know that you don't know.
