  </code></pre>
  
  <p>I am trying to make it into a xts file using</p>
  
  <pre><code>&gt; table3&lt;-xts(table[,-1],order.by=table$Date)
  </code></pre>
  
  <p>but I get this error:</p>
  
  <pre><code>Error in xts(table[, -1], order.by = table$Date) : 
    order.by requires an appropriate time-based object
  </code></pre>
  
  <p>Where did I go wrong? I thought that the table$Date were organized as time-based.</p>
