Taking control of animations in R and demystifying them in the process
A while ago (a very long time ago some would say) I showed how I had created my logo using R. In that post I left on the bombshell that I would return and show you how it is possible to add some fancy animation to it. The time to do that is now! During this post I will go in depth with how it is possible to make very fancy and custom animations...

Reigniting the fire: A roadmap for fiery
