I had a look on yhe proof of concept here (thanks) :
So for now there's nothing suitable for pluginR so far via shiny? I can guess that a pluginR-shiny would be great! Like, for instance, a graphic view of two panels : ui.R & server.R, that stores the files in a random directory on the webserver and starts shiny.server to create the data in an iframe or in the page whenever you load the page...
I was wondering if there was anything new since May? I will try to build in this case generic shiny apps in specific subfolders of our webserver, not using pluginr for now.
