  <pre><code>var myObject = {a: 1, b: 2, c: 3, d: 4};
  
  var newObject = R.filter(R.props('a'), myObject);
  //var newObject = R.filter(R.equals(R.props('a')), myObject);
  
  console.log('newObject', newObject);
  </code></pre>
  
  <p>Right now the code above is returning the entire object:</p>
  
  <p><code>newObject
  {"a":1,"b":2,"c":3,"d":4}</code></p>
  
  <p>What I would like to do is just return a new object with just the <code>'a'</code> key. Or a new object with the <code>a</code> and <code>b</code> keys.</p>
