title: Creating a Unique Sequence of Dates
body: <p>Let's say that I want to generate a data frame which contains a column with 
  is structured in the following format.</p>
  
  <pre><code>2011-08-01
  2011-08-02
  2011-08-03
  2011-08-04
  ...
  </code></pre>
  
  <p>I want to know if it's possible to generate this data with the <code>seq()</code> command.</p>
  
  <p>Something like the following: (obviously doesn't work)</p>
  
  <pre><code>seq(2011-08-01:2011-08-31)
  </code></pre>
  
  <p>Would I instead have to use toDate and regex to generate this date in this
  specific format.</p>
