There is nothing different in the R console than the usual:
Loading required package: shiny
Listening on http://127.0.0.1:6695
But in the web page the following happens:
# No UI defined
Shiny couldn't find any UI for this application. We looked in:
* `www/index.html`
* `ui.R`
* `app.R`
To try my app, you can simply install the QCA package from CRAN, load it and type the command:
runGUI(), which is essentially a wrapper to runApp() but automatically supplying the path to the directory where the app resides.
I hope this helps,
