How to Make a Contour Map

Filled contour plots are useful for looking at density across two dimensions and are often used to visualize geographic data. It’s straightforward to make them in R — once you get your data in the right format, that is.

The familiar but underused layout is a good way to look at patterns over time.

Drawing Circles and Ellipses in R

Whether you use circles as visual encodings or as a way to highlight areas of a plot, there are functions at your disposal.

The Baseline and Working with Time Series in R

A big part of statistics is comparisons, and perhaps more importantly, to figure out what to compare things to. Perspective changes with the baseline.

The American Time Use Survey recently released results for 2018. That makes 15 years of data. What’s different? What’s the same?

Watching the Growth of Walmart

The ever so popular Walmart growth map gets an update, and yes, it still looks like a wildfire. Sam’s Club follows soon after, although not nearly as vigorously.

Redefining Old Age

What is old? When it comes to subjects like health care and retirement, we often think of old in fixed terms. But as people live longer, it’s worth changing the definition.
