Does anybody have experience with creating sandboxes for users/readers of an online publication – in this case for R code?
What I want seems to be in between JupyterHub with an R-kernel and Shiny. But my audience is far from first rate programmers, so Jupyter is kind of giving them a tank where they need a squirt gun. Shiny looks like a way to create a nice and (indeed) shiny user experience, which would cover about 90% of what I need. But I would want the user also to be able to meddle around with a tiny piece of code and see the output within the site (much like JSFiddle).
I know, I know… security alert, hacking red flags, I know. But if I wanted that, what are my options?
