Get your Tidyverse learning boost
We all want to get better with Tidyverse. But the reality is that many of us hit a plateau at some point. To break through that plateau, sometimes you need a learning boost. And that's what this course is all about. I call it the Tidyverse Booster.
Why would you need a Tidyverse Boost?
The tidyverse package consists of hundreds of functions with thousands of arguments. Most of us will work with only a portion of them. This is totally fine and you are probably able to solve your problems with this subset of functions. But what if you took some time to learn about the hidden features of Tidyverse?
Well, you can spend many hours reading hundreds of blog posts and tweets. That's exactly what I did. But the journey was long and took up many of my weekends.
That's why I want to give you a tidyverse boost. Over the last months, I have been packaging up all the tricks and secrets I could find about the tidyverse package into this email course.
How does this course work?
This course will start as an email course. Starting in July 4 2022, you will receive an email every week with a new tutorial on a specific tidyverse topic. Of course, if you sign up later, you will have access to all previous tutorials here on Gumroad.
For each tutorial, I invite you to try the tricks yourself and post your results on Twitter (#tidyversebooster).
Once we're done with all the tutorials, you'll get access to a comprehensive pdf book with all the tutorials we've covered in this course.
What will you learn?
The course consists of 11 chapters. Each chapter addresses a particular topic and is packed with many tricks and secrets about the tidyverse package. Here is an overview of what we will cover (some topics might still change during the course):
