In episode 210 of the R Weekly Highlights podcast: The Positron IDE has officially been released after two years of intense development, and we share what excites us the most. Plus a new tool in your Shiny testing toolbox to bridge the gap between server-side and dynamic updating the user interface, and an entry point to making that URL of your Shiny app set inputs on the fly, a topic one of your hosts has been investigating for quite some time!
