title: Direct link to tabItem with R shiny dashboard
body: <p>I am using the shiny dashboard template to generate my web UI. </p>
  
  <p>I'd like to dynamically generate an infobox when a computation is completed with a link directed to one of the tabItems in <code>dashboardBody</code>.</p>
  
  <p>For example,
  I can put this in my <code>tabItem1</code> output, </p>
  
  <pre><code>renderInfoBox({
    infoBox("Completed", 
      a("Computation Completed", href="#tabItem2"), 
    icon = icon("thumbs-o-up"), color = "green"
    )
  })
  </code></pre>
  
  <p>But the problem is that when I click the link, it does nothing. I would like it jumps to <code>tabItem2</code>. The link href seems valid when I hover on it. </p>
  
  <p>Thanks!</p>

  <p>Update:
  Other than using Javascripts, looks like using <code>actionLink</code> and <code>updateTabItems</code> functions in <code>shinydashboard</code> package will work as well. </p>
