When I run a Shiny App either an example or my own it starts a new window, freezes and then aborts. It tries to listening to a local port then starts a new session.
Details of my system:
My R version: 3.1.3 on MacOS Maverick
other attached packages: [1] shiny_0.12.0 Rcpp_0.11.6
loaded via a namespace (and not attached):
[1] digest_0.6.8 htmltools_0.2.6 httpuv_1.3.2 mime_0.3 R6_2.0.1
[6] tools_3.1.3 xtable_1.7-4
What I tried so far:
From different internet forums I found a lot of suggestions:
I reinstalled Rstudio.
I updated all the packages
Tried this: install.packages(c("Rcpp", "httpuv", "shiny"))
Loaded Rcpp and httpuv separately
tried to run like this runApp('app1',host="127.0.0.1",port = 3894)
// tried other ports as well.
But nothing works. (Please note that, I don't know whether it's relevant but GoogleVis Demo worked on my RStudio.)

Open the app. R script in your RStudio editor. RStudio will recognize the Shiny script and provide a Run App button (at the top of the editor). Either click this button to launch your app or use the keyboard shortcut: Command+Shift+Enter (Control+Shift+Enter on Windows).
You might be eager to deploy your Shiny app to a remote server. But the simplest way to run a Shiny app is to run it locally. You only need the shiny R package installed, and you can run the app in your browser. In this post you'll see a few ways of how to organize your files to be served locally.
A Shiny app consists of two parts, a user interface ( ui ) and an R session that runs code and returns results ( server ). These two parts can be in their own files called ui. R and server. R, or they can be combined into a single file called app.

My recommendation is first to test and confirm R is correctly setup on your machine. We can then move to harness a Shiny demonstration application and confirm if that works.

Can you please run the following command via R, this should download and install shiny and its dependencies...
> install.packages("shiny", dependencies = TRUE)
If things work after this, great. If not, well, then let's check your R configuration:
To check your configuration, my recommendation is you launch R on your machine and run the following tests and post back the output.
> R
> sessionInfo()
Sys.setenv(LC_COLLATE = "C", LC_TIME = "C", LANGUAGE = "en")
library("tools")
testInstalledBasic("both")
testInstalledPackages(scope = "base")
testInstalledPackages(scope = "recommended")
testInstalledBasic("internet")
Once you post the output of the above command set, we can move to work through the example 'World Bank', and see if we can determine the problem.
Take care
