title: Accessing a column in scikit dataset
body: <p>I am loading the built-in boston data set in scikit library as:</p>
  
  <p><code>
  from sklearn.datasets import load_boston
  bdata = load_boston()
  </code></p>
  
  <p>I want to extract all the values in the first column, which is called as CRIM. I Have written a line like:
  <code>
  plt.scatter(bdata.CRIM,bdata.target,color='blue')
  </code></p>
  
  <p>But I am getting an error as "AttributeError: 'Bunch' object has no attribute 'CRIM'"</p>
  
  <p>How do I access the elements of the column titled 'CRIM' ?</p>
