title: Pandas resampling using numpy percentile?
body: <p>Have you ever used the percentile numpy function when using the pandas function resample??</p>
  
  <p>Considering that "data" is a dataframe with just one column with 10min data, I would like to do something like this:</p>
  
  <pre><code>dataDaily=data.resample('D',how=np.percentile(data['Col1'],q=90)
  </code></pre>
  
  <p>I got the following error:</p>
  
  <pre><code>'numpy.float64' object is not callable
  </code></pre>
  
  <p>Have you ever try this?</p>
