title: Putting a repeating value into a column
body: <p>I feel dumb asking this but here goes.  I have a list of numbers but I want to combine it with date.  </p>
  
  <p>for instance:</p>
  
  <pre><code>list1 &lt;- c(1, 2, 3, 4, 5)
  list2 &lt;-c("2009-01-01")
  list3 &lt;-cbind(list2, list1)
  </code></pre>
  
  <p>I want the SAME date listed the same number of times as there are data points and then combined with the data points.  </p>
  
  <pre><code>date                number
  "2009-01-01"          1
  "2009-01-01"          2
  "2009-01-01"          3
  "2009-01-01"          4
  "2009-01-01"          5
  </code></pre>
  
  <p>When I try to run the above code I get the message about lengths not matching. Any suggestions are appreciated.  Thanks.</p>
