title: Why my app doesn't deploy on shinyapps.io?
body: <p>I followed the same commands shown in <a href="https://www.shinyapps.io/admin/#/dashboard" rel="nofollow noreferrer">shinyapps.io</a> for uploading my app but I get the following error:</p>
  <pre><code>&gt; library(shinyapps)
  &gt; shinyapps::deployApp(&quot;/Users/mona/CS764/demo&quot;)
  Error in lint(appDir) : Cancelling deployment: invalid project layout.
  The project should have one of the following layouts:
  1. 'shiny.R' and 'ui.R' in the application base directory,
  2. 'shiny.R' and 'www/index.html' in the application base directory,
  3. An R Markdown (.Rmd) document.
  </code></pre>
