Feed: R-bloggers. Author: Tony Hirst. Inspired by some 3D map views generated using the rayshader and rgl R packages, I wondered how easy it would be to render some 3D maps of rally stages. It didn’t take too long to get a quick example up and running but then I started wondering what else I could do with route and elevation data. And it turns out, quite a lot. The result of my tinkerings to date is at rallydatajunkie.com/visualising-rally-stages. It concentrates soley on a “static analysis” of rally routes: no results, no telemetry, just the route. Along the way, it ... Read More

Feed: R-bloggers. Author: Econometrics and Free Software. Introduction I was able to blog during the year 2020 without mentioning the ongoing pandemic once. It’s not that I made any conscious effort not to talk about it, but I did not really want to do something that had already been done a 1000 times. This changed this year, when I wanted to look at the spread of COVID-19, not only in the Grand-Duchy of Luxembourg, the country I live in, but also among our neighbours. You see, the Grand-Duchy of Luxembourg is like an island, but instead of being surrounded by ... Read More
