title: Replacing specific values in dataset with Azure ML
body: <p>Lately i've been testing Azure Machine Learning, and i like it. However, when i try to transform my dataset, there's a step that i can't perform easily : replacing a specific value in a column by another one.</p>
  
  <p>The <code>Missing Values Scrubber</code> module allows me to deal with undefined values, but in my case i need to change a specific value, or remove rows where that value appears. I don't see which module meets my requirement.</p>
  
  <p>Do you have any suggestion about this issue ? </p>
