Hello! I am Daran Johnson. Welcome to my blog! 👋
Data has been a part of my life for a few decades now. I currently run a consulting company (Fujo Analytics) that focuses on providing analytics, mainly in the area of digital marketing & ecommerce. I concentrate on creating analysis that is well-documented, easily reproducible, simple to share and robust. Generally, the way to do that is by understanding how to code.
I really love the R programming language, and it is my go to when it comes to data analysis. I was looking for a better data visualization tool some years ago and stumbled upon R. I got so much more than that. Here are some of the reasons I like R so much:
- Reproducibility – R is code, so any analysis that you do in R can be run any where. Watch this simple analysis by Hadley Wickham and imagine doing this in Excel. It’s not that you can’t, but it’s a lot more work.
- RMarkdown – Like markdown, but with R. This can take the place of blog pages (most of my blog is written in RMarkdown), PDFs, PowerPoint, and many other formats. The advantage of using RMarkdown is reproducibility, customizability, and the ability to directly pull data into the document and prep that data and display it in very customized charts and tables. I have found it to be perfect for A/B test result papers.
- People – The community of people that use R are awesome! Since R is open-source, it is accessible to anyone that has a computer. And since R is a statistical programming language, it is used mainly by people focused on some kind of data analysis – from students and Professors to Data Scientists and Data Analysts. Scientists use R, so do business people. They tend to to share a lot – from code snippets to package development (GitHub has been great for this).
I think it’s important to never stop learning. I am always studying one book or another and I love a good textbook. A couple of my favorite textbooks are:
- Chris Date’s An Introduction to Database Systems – Few textbooks are as in-depth on the subject of relational database systems as this one. This book taught me to see data structures in a whole new way.
- Andy Field’s Discovering Statistics Using R – I think this book is revolutionary in how it is structured. First of all, it teaches you R and statistics at the same time. As you study each chapter, the data is interesting and/or funny and Andy Field inserts his own life in the the chapters, so the book doesn’t have that stoic academic anonymity to it. Of all textbooks I have ever studied, this is my favorite.
- Andy Field’s An Adventure In Statistics – This book teaches statistics as the story of Zack, who wakes up to find his soulmate, Alice, has vanished. He must use statistics to locate her. The illustrations are better than any textbook I’ve studied and the approach to teaching the material is on a whole different level.
This website is about sharing my understanding of analytics, mostly focused on the use of statistics, R and SQL. Any post focused on coding a functional app will have the full code available on GitHub. I also strive to have a workable example available, if possible.
I don’t have the comments on because it’s easier to just reach out through the methods below. I encourage you to reach out to me. Let me know if the content of this blog is helpful or just confusing and hard to follow. Maybe you just have a simple question, comment or topic you would like me to cover – reach out. I really want to make the posts as relevant as possible.
I’m also an avid runner and Strava has a great running group for R programmers called The RStats Running Club which I am active on. So if you run and you like R, please join.
If you have questions or just want to chat, here are a few easy ways to get in touch with me. You can email me directly at daranjjohnson (at) gmail.com. You can also check out my LinkedIn profile. I check my LinkedIn messages often. I am also active on Twitter.
