This is the final cohort of R in 3 Months. After this fall, there won't be another one.
I’ve often been asked: “how long does it take to learn R?” I’ve never had a good answer ... until now.
Here’s my answer: 3 months.
Give me 3 months and I’ll get you to the point where you can use R for all of your data work.
Learning R will save you time and money.
High-Quality Instruction
With R in 3 Months, you’ll get high-quality instruction that will guide you from R newbie to R expert.
Over the three months, you’ll go through Getting Started with R, Fundamentals of R, and Going Deeper with R, courses that have helped thousands of people around the world learn R.
Personalized Feedback
Each week, you'll be asked to apply the concepts you're learning to a real project you're working on.
You'll share your code and get personalized feedback to ensure that you really, finally learn how to apply R to your work.

Alongside a Supportive Community
You'll be on this journey alongside a supportive community that will help you learn and keep you accountable to yourself.
R in 3 Months will use a flipped classroom model. Each week you’ll be assigned to complete a set of lessons. Then, in our weekly live session (check out the sample video) we’ll go over questions related to the concepts in the lessons you completed that week and discuss ways that you’re applying your learning to your own work.
“I’m wrapping up the R in 3 Months course through R for the Rest of Us now, and it’s been the best professional development experience of my life, hands down.
Don't take it from us
Our learners say it best.
“I’m wrapping up the R in 3 Months course through R for the Rest of Us now, and it’s been the best professional development experience of my life, hands down.
“For anyone wanting to learn R, I cannot recommend this course enough!
“I think one of the biggest benefits of R in 3 Months is having continued access to all of the resources. Thanks so much for making that available to us!
“I have been working with R for the past 3 years and consider myself to be a proficient user, however going through R in the 3 Months course made me realize the breadth of possibilities R offers and how much more there is to learn. I was able to pick up so many handy tricks that made my R workflow much more efficient and easier to reproduce.
“I'm extremely proud and happy to announce that in March I received a scholarship for R 3 in Months Course by R for the Rest of Us thanks to David Keyes and Charlie Joey Hadley. I want to express my deep appreciation for this amazing program, which is greatly helping me in significant professional growth. Their expertise, dedication, and commitment to helping students succeed in their different fields using data analysis and visualization in R is admirable and praiseworthy. Doing this course was definitely an enjoyable experience. Eternal thanks to R for the Rest of Us and to David & Charlie.
“After learning R through self-study and short courses, I realized my knowledge was fragmented—I understood pieces but lacked a clear conceptual map. R in 3 Months by David Keyes has been transformative: its well-structured videos, hands-on exercises, and live sessions helped me connect those pieces and finally see R as a coherent system rather than a collection of disconnected tools. It also helped me tackle a persistent challenge: forgetting functions and their underlying logic by showing me how to effectively leverage AI to refresh my memory and uncover unexpected connections. The support of Gracielle Higino has been equally invaluable, making the learning process both effective and encouraging.
“As we get to the end of the course, I'm feeling so much stronger in my ability to work with my data and make the visualizations I need. In the first part of the course I kept thinking, "I'm not sure if this is more time-efficient than using Stata"; later on I felt that it would be best to do my data wrangling in Stata and my data vis for maps and complex plots in R; and now I'm starting most of my new projects in R, as RMarkdown files, and planning forthcoming analyses with collaborators in R.
“One of the most informative courses I have ever taken. The weekly videos are extremely helpful and show step by step how to code in R. In addition, you will have access to these videos even after the course finishes. I was very confused on how to use R just by reading books, but after this course I feel a lot more confident in R.
“I just want to say how much I enjoyed R in 3 Months with R for the Rest of Us. It was a really great course. I was very intimidated to learn R. I finished my PhD and we were mostly working with SPSS and I started a new role where it became apparent that I needed to use and learn R pretty quickly. David and Charlie were great in helping me get up to speed and start working in R nearly every day. They make it quite fun and enjoyable to learn how to start exploring this great new, wonderful world of R. I got a lot of individualized attention and so it's a great course. I couldn't recommend it more.
“My team is continuing to use the R we learned from you and your team - it's been a game changer for us and we've only scratched the surface on what we know how to do.
Three courses that all fit together, taking you from R novice to R expert.
Ask questions about the lessons, show how you're applying your learning to your own work, and more.
When topics come up in live sessions, we make exclusive videos to demonstrate concepts.
No need to wait until the next live session! Ask questions any time and get answers when you need them.
Through live sessions and the forum, you'll get personalized feedback on how you're applying your learning to your own work.
Don't go it alone! Learn R with others and help each other stay on track.
Live sessions are held on Zoom Thursdays from 10:00am - 11:00am Pacific time from September 17 to December 17.

Final Projects and Wrap-Up
At the end of R in 3 Months, participants submit a final assignment to show what they learned. Here's how far you can go in 3 months.
We don't just know how to use R. We know how to teach R.
Learning R is an investment in your future
Deadline to sign up: September 22
This is the final cohort of R in 3 Months. There won't be a next time.

We want to make R accessible to as many people as possible so we offer three scholarships for R in 3 Months. We will prioritize those underrepresented in the R community in deciding who will receive the scholarships. Deadline to apply is September 15.
Forever!
You’re right, there are a ton of free tutorials. You can learn R using free resources. I did! But, I will say that, looking back, I know I spent much longer than if I had taken a more structured approach. Going through R in 3 Months, you benefit from the mistakes I’ve made by taking the shortest route on your R journey.
Yes! You can sign up for the free Getting Started course or check out sample lessons in the Fundamentals or Going Deeper courses.
Here is a sample video from the spring 2025 cohort of R in 3 Months.
You should plan to spend 5-7 hours per week devoted to R in 3 Months. The breakdown of this is: weekly lessons from courses (2-3 hours), application of new concepts to your own work (2-3 hours), live session (1 hour).
Absolutely not! I’m an anthropologist by training. I’ve written about coming to terms with using R “only” for descriptive stats. R has a reputation for being only for hardcore quants, but it’s a tool that can benefit so many more people. That’s what I mean when I talk about “R for the Rest of Us.” That said, you should have familiarity with things such as data types (e.g. character versus numeric) as well basic descriptive statistics knowledge (e.g. calculating means etc).
People who have never programmed before are the exactly type of folks I specialize in helping (you are "the rest of us")!
Nope! You'll start out with my Getting Started with R course, which assumes you've never used R before.
Nope, just a computer! We'll show you how to download all of the free software needed to participate.
Yes! I expect that not everyone will be able to participate in all live sessions, given time zones and/or life. All live sessions will be recorded and posted by the next day so you can catch up whenever you're able to.
I chose this approach for two reasons.
Practically speaking, allowing folks to complete lessons on their own schedule makes this program accessible to many more people around the world.
Just as importantly, I chose to do a flipped classroom model because I think it is the most effective way to learn. I've taught the material covered in the Fundamentals and Going Deeper courses live. The challenge is that participants want to move at widely varying speeds. While some people want to go fast, others prefer a slower pace. A middle ground, medium pace often pleases few and frustrates many. Using a flipped classroom model enables everyone to work at their optimal speed for learning.
Absolutely! Just send me an email and I'll create a coupon code that gives you a discount equal to the amount you've spent to sign up for these courses.
No. Fall 2026 will be the last cohort of R in 3 Months. I'm launching Ally, our program for learning to use AI effectively with R, on October 6, and R in 3 Months is too time-intensive to run alongside it. This cohort isn't a scaled-back version, though. We're running it exactly the way we've run the last 11.
If you want the program, yes. Everything you get is yours forever: the lessons, the project assignments, the recording of every live session, and any feedback you receive on your projects. The only thing that ends with the cohort is new feedback, since no one will be reviewing submissions after December 17. So submit what you can this fall, and work through the rest on your own schedule.
If you are unsatisfied with R in 3 Months for any reason, contact me in the first two weeks of R in 3 Months and I will give you a full refund, no questions asked.
Yes! As an R in 3 Months participant, you'll receive 50% off your first year of Ally.
