Welcome to the AD&T Consulting R gateway. Here we provide you with the basic skills to start programming in one of the most widely-used and powerful statistical programming languages. Why learn R?

R has its quirks, but we think you'll ultimately find it easy to use and before long, you'll find it hard to function without it. Let's get started.
