Wow, this looks _very_ cool! Thank you for all the R work you do.

Runs with no problems here. Starts a Chrome session on localhost:8100.

>The code for the above shiny app can be viewed or downloaded from

Did that, pasted server.R and ui.R into ~/R/gsee/, then within
an interactive R session, did:

> runApp(appDir = '~/R/gsee', port = 8100L)

It runs as before, and after opening up port 8100, the world can see
it. Amazing. Firefox 16.x and Chrome 20.0.1132.57 both work.

Love to see this in action.

Looks as if it will be very useful indeed. :)

Thanks again,

All of us necessarily hold many casual opinions that are ludicrously
wrong simply because life is far too short for us to think through even
a small fraction of the topics that we come across.
