title: Deedle frame to R
body: <p>I am trying to put some code to work.
  I am using <a href="http://bluemountaincapital.github.io/Deedle/rinterop.html" rel="nofollow">rinterop</a> as a reference.</p>
  
  <p>I have a <code>Frame&lt;DateTime,string&gt;</code> which I try to send over to R using</p>
  
  
  
  <pre class="lang-ml prettyprint-override"><code>let frame = 
      let aSerie = 
          Series.ofObservations 
              [ DateTime(2013,1,1) =&gt; 10.0
                DateTime(2013,1,4) =&gt; 20.0
                DateTime(2013,1,8) =&gt; 30.0 ] 
      Frame(["Hello"], [aSerie])
  R.as_data_frame(frame)
  </code></pre>
  
  <p>which gives the following:</p>
  
  <blockquote>
    <p>System.Exception: No converter registered for type
    Deedle.Series`2[[System.DateTime, mscorlib, Version=4.0.0.0,
    Culture=neutral, PublicKeyToken=b77a5c561934e089],</p>
  </blockquote>
  
  <p>I also tried the following example:</p>
  
  <pre class="lang-ml prettyprint-override"><code>let rnd = Random()
  let ts = 
    [ for i in 0.0 .. 100.0 -&gt; 
        DateTime.Today.AddHours(i), rnd.NextDouble() ] 
    |&gt; series
  R.as_zoo(ts)
  </code></pre>
  
  <p>which result in the same kind of error:</p>
  
  <blockquote>
    <p>System.Exception: No converter registered for type
    Deedle.Series`2[[System.DateTime, mscorlib, Version=4.0.0.0,
    Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Double,
    mscorlib, Version=4.0.0.0, Culture=neutral,
    PublicKeyToken=b77a5c561934e089]] or any of its base types</p>
  </blockquote>
  
  <p>My ultimate goal is to chart Deedle frames, with <code>DateTime</code> as row keys using R.</p>
