Review: Going from Beginner to Advanced in ggplot2 — Udemy Course
Hi, it’s me Ola. It’s been a while since I’ve made a blog post. It's been about 3 years to be exact. Let me re-introduce myself. I am a data analyst who also knows front-end development. I have this on-again-off-again relationship with the R language. Every professional data analyst job that I have uses Python. I mean it is called the Swiss Army knife of programming languages. Despite this R keeps calling my name.
So I decided for the millionth time to learn R again. I decided to buy this course Going from Beginner to Advanced in ggplot2 by Christian Burkhart when it was on sale. And it's pretty good. The most useful themes from this course for me are aesthetics, geoms, scales, and theme(combine all of these and you get the grammar of graphics). The course includes stand-alone lessons to process the material. With each chapter, there are about 4 major plots that you will apply what you learned from lessons 2 to 9. The instructor also has ggplot2 cheat sheets/ apps that helped me create data vizzes with ggplot2 at ggplot2tor. The cheat sheets are completely free for anyone to use and you don’t need to sign up for the course.
ggplot2 is a very extensive language and it's just nice to have one go-to resource instead of searching through stackoverflow to figure out how to replicate the graph.
I am a complete data visualization guru after taking this course. Absolutely not. I know that will take a lot of practice. And me making a lot of bad data visualizations before I start getting the hang of design. But after taking this course I feel confident that I know the fundamentals of ggplot2.
