When I started Colibri Consulting I knew I would need to up my game on data analysis and visualization, and I knew that meant learning R. Finding the R in 3 Months course was a fantastic way to start that journey. I love that you can customize every chart down to the smallest detail in RStudio and build reports interlaced with beautiful graphics.

David, Just a note to say thank you for a clear, concise and straightforward approach to R. Shout out to Chris Garmon, University of Missouri-Kansas City, MO professor in graduate school course, Research Methods in Public Administration for steering students to your free, easily understandable course. You do a great job taking the scariness out of R by taking us step by step through learning how to use R and explaining the power R has in being able to tell a story through data and analyzing information to make decisions. Professor Garmon told us that The Washington Post uses R for it's data and that's quite a seal of approval. Thanks again for a great course. Bernita Cauthon, Kansas City, Missouri

I started learning R and GGPLOT by relying on books (e.g., R for Data Science) and youtube. This left me with a fragmented knowledge, since few of these sources approached teaching R and GGPLOT from a holistic manner. Getting Started with R patched up many of those holes, while giving me with invaluable tips as to how to secure future advise and support.

Before starting R in 3 Months, I had completed several courses on R. However, they all felt generic—focused more on transitioning from learning to simply acing exercise questions, which, in the age of AI, isn't particularly challenging. This course, however, was different. It felt like I was truly in a classroom setting. Even while watching the pre-recorded videos, it struck the perfect balance between self-paced learning and providing the push I needed to stay motivated and engaged. Without a doubt, R in 3 Months is the best course I’ve taken this year.

This was a great course for me, just starting to use R and now I got just the introduction I needed to be up and running using R.

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.

This is an excellent introduction to R and Rstudio and the capabilities of R. It was easy to understand and the exercises and tips were very helpful. I learned a lot. Thank you for offering this us to dip our toes into using R.

Eric Excellent beginner course...

Hello, i really appreaciated the way the actions in R were described. However, i still struggle to understand the concrete benefit of R. I am wondering, wheter R can do controlling reports as well ? I mean, i work for a retail company, and every month i have to prepare revenue, profit reports of sales of the different product groups. I usually prepare these reports in Excel..... so i monthly have to export all the necassary data from our ERP-System into Excel sheets and then i have to collect and prepare them in one report. Do u think R Studio can do the same thing so that it is less effort for me?

This course is fantastic! I can't say enough good things about it. There were a few basic functions that I had already learned in R but I had always struggled with retaining the information because I'd never quite understood the grammar around how to piece functions together. David breaks down everything into really easy to understand and digestible chunks. I was asked to complete an assessment in R for a job interview only 2 days after finishing this course; I was able to complete the assessment and was asked to progress to the next stage of interviewing. With a lifetime access, this course is well worth the money. I would 100% recommend this course to a friend or colleague.

I consider myself lucky as I found Mr. David's courses in R. I loved every single tutorial in this course. What I love most about this course is that it teaches you bit by bit and step by step, literally from zero to hero. I'll recommend these tutorials to anyone interested in R programming. I'll take the next course, "Going Deeper with R." I have no intention of stopping until I finish every tutorial on this website. Thank you so much, Mr. David. I owe you a lot. Greetings from Egypt.

As someone who has never coded before, this course was a lifesaver. Dr. Keyes takes you on an incredible journey as he follows a step-by-step approach to familiarise you with R and making it less intimidating to code. This course has encouraged me to continue learning R and hopefully, become proficient in it in the coming future.

Gone are the days of copy-pasting SPSS output to Excel, and Excel charts to Word, over and over again! Learning R was one of the best professional investments I have ever made, and has been invaluable in streamlining my work UBC Faculty of Medicine and the Justice Institute of British Columbia.

It was a great quick start into how to use R. Thank you so much!
