As I explained in my previous blog post, in June 2023 I drove my family across the country in a 5,000-mile roundtrip odyssey from Atlanta, Georgia to just-south-of-Salt Lake City, Utah, and back again.
In a couple days, I’m going to drive across the country to Utah, my home state. I haven’t been out west with my whole family in four years—not since 2019 when we moved from Spanish Fork, Utah to Atlanta, Georgia. According to Google Maps, it’s a mere 1,900 miles (3,000 kilometers) through the middle of the United States and should take 28 hours, assuming no stops.
.magic-block { font-style: normal; user-select: none; padding: 0 0.1em 0 0.15em; line-height: 1; font-size: 120%; } I’ve been working on converting a couple of my dissertation chapters into standalone articles, so I’ve been revisiting and improving my older R code.
I’ve taught a course on data visualization with R since 2017, and it’s become one of my more popular classes, especially since it’s all available asynchronously online with hours of Creative Commons-licensed videos and materials.
In The Two Towers , while talking with Eowyn, Aragorn casually mentions that he’s actually 87 years old. When Aragorn is off running for miles and miles and fighting orcs and trolls and Uruk-hai and doing all his other Lord of the Rings adventures, he hardly behaves like a regular human 87-year-old. How old is he really?
Pandoc-flavored Markdown makes it really easy to cite and reference things. You can write something like this (assuming you use this references.bib BibTeX file): --- title: "Some title" bibliography: references.bib --- According to @Lovelace:1842, computers can calculate things.
My longstanding workflow for writing, citing, and PDF management When I started my first master’s degree program in 2008, I decided to stop using Word for all my academic writing and instead use plain text Markdown for everything. Markdown itself had been a thing for 4 years, and MultiMarkdown—a pandoc-like extension of Markdown that could handle BibTeX bibliographies—was brand new.
I always forget how to deal with logged values in ggplot—particularly things that use the natural log.
As a field, statistics is really bad at naming things. Take, for instance, the term “fixed effects.” In econometrics and other social science-flavored statistics, this typically refers to categorical terms in a regression model.

In one of the assignments for my data visualization class, I have students visualize the number of essential construction projects that were allowed to continue during New York City’s initial COVID shelter-in-place order in March and April 2020. It’s a good dataset to practice visualizing amounts and proportions and to practice with dplyr ’s group_by() and summarize() and shows some interesting trends.
