Launching shiny from a command line

[PF]

I am having trouble launching shiny from a command line - when I execute the runApp from within an rGui/rStudio it launches a firefox window and works, but when I run R from a command line and pipe in the same script (which is just a wrapper) the program hangs at "Listening on port 8100" - is there a browser setting that needs to be set when running it from the command line? I have added the browser directory to my path.

call is
R --no-save  < shinyLoader.R

OS Windows 7, Browser Firefox v19, R 2.15.2, RStudio

Thanks
Peter

It is working but by default Shiny doesn't automatically launch a
browser if it's running in a non-interactive R session. You can force
it to launch a browser anyway by passing the "launch.browser=TRUE"
argument to runApp.
