Using Shiny with shinyjs, we can capture clicks/selections via inputs to redirect to another app. In this example, I posted three strawman apps in adjacent directories.
Using various package examples as a basis, built simple prototype of an app that demonstrates how to clear all inputs/outputs in related apps without app refactoring, etc. In response to Google Groups thread by Sylvain on 2016-12-14 at https://groups.google.com/forum/#!topic/shiny-discuss/YODirLvqH4c
In simplest case, you would place your apps in adjacent directories /app1/app.R /app2/app.R /app3/app.R
