title: Split a string by any number of spaces
body: <p>I have the following string:</p>
  
  <pre><code>[1] "10012      ----      ----      ----      ----       CAB    UNCH                    CAB"
  </code></pre>
  
  <p>I want to split this string by the gaps, but the gaps have a variable number of spaces. Is there a way to use <code>strsplit()</code> function to split this string and return a vector of 8 elements that has removed all of the gaps?</p>
  
  <p>One line of code is preferred. </p>
