Revisited: Animating 2020 running goals - and compare them with previous years

Picking up the pieces Recently, I’ve animated a specific running goal for one year with data from the Strava API. I thought it would also be nice to compare different years within the same animation - in a way you could say that you’re racing yourself over several years. This only needs some minor modifications to the code I posted before. Data collection stays basically the same, so I’m just re-posting this here.

'Running through the fields, lying flat on the ground': Animating 2020 running goals

Full disclosure: I did not even have any running goals for 2020. But as it turned out: It has been a good year for running - at least one thing this year was good at. In this post, I want to run you through my R script which creates an animated graph that looks like I had the goal of running 500 kilometres this year (spoiler: I didn’t). This is what the finished graph looks like (for 2020-12-23):
Let the snail crawl: Animated density curves

Let the snail crawl: Animated density curves

Previously, I’ve plotted a ridgeline based on a variable’s density through time. It might look nice but it’s quite obvious that time can be visualized in a more fitting way - by time itself, in an animated plot that is. So, let’s fire up the {gganimate} package again. My goal is to show a moving kernel density curve as it moves through time, based on a moving window of 30 days sliding from the past to the present.
Correspondence Analysis visualization using ggplot

Correspondence Analysis visualization using ggplot

What we want to do Recently, I used a correspondence analysis from the ca package in a paper. All of the figures in the paper were done with ggplot. So, I wanted the visualization for the correspondence analysis to match the style of the other figures. The standard plot method plot.ca() however, produces base graphics plots. So, I had to create the ggplot visualization myself. Actually, I don’t know if there are any packages that take a ca object (created by the ca package) and produce ggplots from it.
