Here’s What Is All About

Hey, welcome. I’m Guangming Lang, the owner of, and if you ever asked yourself:

  • “I want to learn R, and where do I start?”
  • “How can I become better at R?”
  • “How can I become really awesome in R?”

Or if you’ve ever just needed to quickly find the right R function to do your task at hand…

…You’re in the RIGHT place!

Here’s How Helps You Become Great at R

As the chief economist at Google Hal Varian said, “the sexy job in the next 10 years will be statisticians.” As Forbes’ one of the world’s 7 most powerful data scientists DJ Patil said, “data scientist is the sexiest job of the 21st century.” I’m here to teach you the most powerful tool statisticians or data scientists use in their everyday work: R.

Here’s the deal:

I believe great statisticians and data scientists who want to win in today’s job market MUST also become master R programmers.

Now, there’re tons of R learning materials out there. In fact, too many to tell which ones are excellent and which ones are bad, which ones are useful and which ones are useless. How can you find the time to sort all these out and learn by yourself while catching a deadline… while taking 5 classes… while working a full-time job…

Instead of digging through hundreds of books, thousands of stack overflow QAs, tens of thousands of google searches, and wasting time on dry materials or materials that talk about the less often used R features…

…subscribe to (it’s free), and you’ll get the most effective R training materials and best tips from me, Guangming Lang.

And the best part? I’ll cut through the fluff, showing you exactly what’s going on step by step, and giving you exectly the R code data scientists write to solve practical real world problems.

All because I have a knack for explaining how things work in R intuitively, and for writing INSANELY PRACTICAL RE-USEABLE R functions and packages that you can start benefiting from TODAY.

Introducing (The Blog and The Videos) is a thriving community of statisticians and data scientists who want to become better at R.

There’re two main features of There’s the blog and there’re videos. When you subscribe for free email updates, you’ll gain access to all two PLUS exclusive “email only” material (I treat my email subscribers the best).

Here’s what each “feature” is all about:, the blog, is where you’ll get proven R scripts that you can use in your study and work. Some scripts are about data cleaning. Others are about data analysis. You’ll also get articles that help you understand certain statistical concepts and data analysis techniques.

gmlang videos, are short 2 to 5 minute videos where I’ll use R and RStudio to demo, step by step, a simple how-to task that you can follow along and master TODAY.
