title: R filter function won't filter out results
body: <p>I'm trying to find all rows where values exist between a top and bottom depth value in Azure ML. I'm using dplyr's filter function, and the code doesn't throw an error. But when I look at the results it hasn't filtered anything. Can somebody see where I'm going wrong?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>library(dplyr)
  
  Upper_Depth&lt;-dataset1$Upper_Depth
  Lower_Depth&lt;-dataset1$Lower_Depth
  TopMD&lt;-dataset1$TopMD
  BaseMD&lt;-dataset1$BaseMD
  
    # Filter where the Perf is within the Upper and Lower Depth intervals:
    #select(Upper_Depth, Lower_Depth, TopMD, BaseMD) %&gt;%
    filter(dataset1, Upper_Depth &gt; TopMD &amp; Lower_Depth &lt; BaseMD);
    
    # Subset the data where the perfs are in the L_WSEC_A:
    #subset(dataset1, Upper_Depth &gt; TopMD &amp; Lower_Depth &lt; BaseMD)
    
    full_data &lt;- dataset1
  
  # Select data.frame to be sent to the output Dataset port
  maml.mapOutputPort("full_data")</code></pre>
  </div>
  </div>
  </p>
  
  <p>I tried the subset function but get the same result. I apologize because I'm very new to r and Azure ML Studio.</p>
