title: Shiny: overlapping of renderPlot with fluidrow
body: <p>In the Shiny example <a href="http://shiny.rstudio.com/gallery/plot-plus-three-columns.html" rel="nofollow">http://shiny.rstudio.com/gallery/plot-plus-three-columns.html</a> if we replace the code part in <code>server.R</code></p>
  
  <pre><code>print(p)
  
  })
  </code></pre>
  
  <p>by </p>
  
  <pre><code>print(p)
  
  }, height = 600)
  </code></pre>
  
  <p>we get an overlapping of the graphic window and the inputs below integrated with <code>fluidrow</code>.
  How can we avoid such an overlapping when <code>height</code> is specified in <code>renderPlot</code> ?
  Thanks.</p>
