Summary:

In this video, we use the Positron IDE (Public Beta) to create and render Shiny applications in both R and Python.

In short, you need to install the Shiny VS extension by going to the extensions tab, searching for `shiny` (the non-deprecated one), and then pressing install on the Shiny extension. Alternatively, you can directly go to the extension page on OpenVSX and install it there:

The Shiny for R app was built using the different UI/Server components here:

The Shiny for Python App was built using the first example here:

I created the same app.R file on my desktop. When I try to run the file with the option 'Run Shiny App', I get this error 'Could Not find R. R is installed on your system? If R is installed, please make sure your PATH environment variable is configured correctly'. The same app works perfectly in Rstudio when I use 'Run app'. Did you maybe set something different during the Positron installation? Thanks
