I really only wanted to spill some fountain pen ink. Not literally. That would be expensive. 🖋️ I wanted to take colours inspired by Pilot’s Iroshizuku fountain pen inks, drop them somewhere on a blank canvas, and let them flow. That led me to f...

Zhenguo Zhang's Blog https://fortune9.netlify.app/2026/08/30/r-understanding-position-dodge-and-position-dodge2-in-ggplot2/ - In ggplot2, when displaying grouped data along categorical axes (such as grouped bar charts, boxplots, or error bars), horiz...

One tiny dataset, another rabbit hole 🐇🕳️ In the previous post, I turned 24 Pilot Iroshizuku fountain pen inks into a tiny shop using ggplot2. But while sorting the inks by colour, I started wondering what it would look like if I could rearrang...

Introduction In previous articles, we showed how to test whether two qualitative variables are related thanks to the Chi-square test of independence in R (and how to compute it by hand). Both articles insist on one important limitation: this test requires independent observations. If you have dependent observations (paired samples), ...

Overview       Do people in red states live shorter lives?       This project examines whether state level life expectancy is statistically associated with each state's political climate in t...

We’ve previously extolled the virtues of automating the repetitive chores we encounter, allowing us to focus on the tasks that matter. Three years ago, we posted an example of how to automate the deployment of a Shiny application to shinyapps.io from a GitHub Actions. When a new commit ...

There's no official crosswalk between the ONET's occupational taxonomy and ANZSCO, which is awkward, because Australian researchers use ONET data all the time. This post builds one, explains why you should be suspicious of relying on it and then suggests a better methodology is probably what was applied by the ...

The gap Much of what Bioconductor packages do is interactive and exploratory, and rightly belongs in an R session. But some of it is batch-shaped: a well-defined analysis with file inputs, file outputs, and a handful of parameters. Differential...

Below are the slides for my Futurize - Tearing Down Parallelization Barriers in R with Transpilers talk that I presented at the useR! 2026 conference in Warzaw, Poland. Title: Futurize - Tearing Down Parallelization Barriers in R with Transpil...

Introduction In a previous article, we showed how to perform the Chi-square test of independence in R in order to test whether two qualitative variables are related. As mentioned in that article (and in the one showing how to do the Chi-square tes...
