The concept is simple - I get data from one of the scientists in my group. Or I get my own. Then I demonstrate, step-by-step, how I generate the plot(s). I’ll also toss in some data science concepts occasionally.

They are a bit sparse on the words because I’m presenting these in person. But I believe they are clear enough for someone to follow along. Let me know if I’m wrong.

Tooling

I like R. I like ggplot. I like the tidyverse. That’s what I’ll be using.

How can I follow along?

  1. Download and install R: https://cran.r-project.org/
  2. Download and install Rstudio: https://www.rstudio.com/products/rstudio/download/#download
  3. In Rstudio install any libraries that throw an error when you run library (LIBRARYNAME) with install.packages(LIBRARYNAME)
  4. Download data files (each post should explain how to find them).
  5. Then you can (largely) go line by line through the blog post
