title: Shiny (Rstudio) apps not working
body: <p>I am working on the <a href="http://shiny.rstudio.com/tutorial/lesson1/#Go%20Further" rel="nofollow">Shiny tutorial for RStudio</a>.  I updated my RStudio, as indicated in the tutorial. The current version I have is 0.98.945.  When I run the supplied examples like <code>runExample("01_hello")</code>, it opens my web browser and shows all the HTML content, but does not seem to be processing the R code.  </p>
  
  <p>When I proceed further in the tutorial for creating my own app <code>runApp("App-1")</code>, I get an error message on the web page:  ERROR: could not find function "fluidPage".  After some sleuthing, I found a posting on another site indicating that I need to download the developer version of shiny from GitHub, found <a href="https://github.com/rstudio/shiny#installation" rel="nofollow">here</a>.  I ran the code snippet for that installation -- and still no luck.  Any suggestions would be greatly appreciated!</p>
