  <p>What I want to do now, is to scale the values for each column to have values from 0 to 1. </p>
  
  <p>I tried to accomplish this using the <code>scale()</code> function on my matrix (default parameters), and I got this</p>

  <p>Which is already close to what I want, but values from 0:1 were even better. I read the help manual of <code>scale()</code>, but I really don't understand how I would do that.</p>
