I know I can put them into a vignette, but the advantage of demo files is that you can run them using demo(). It just seems like the facilities for demo files were abandoned.

I converted most of my demo files in rgl to a single vignette. I just added a simple paragraph > This vignette holds code that was previously included as "demos" > in `rgl`. Some of the demos require R to be running; those remain > available via `demo(package = "rgl")`. As the second sentence indicates, rgl still has a few demos, mostly Shiny examples. Conversion was simple: just copy the title into a heading, and include all the code.
