title: Sort descending all columns of data.frame
body: <p>I'm fiddling with this now for a while, but can't find reasonable solution. </p>
  
  <p>I would like to sort in descending order all columns of data.frame. </p>
  
  <p>Sample data for instance:</p>
  
  <pre><code>CustomData &lt;- data.frame(Value1=rnorm(100,1,2), Value2=rnorm(100,2,3),
                           Value3=rexp(100,5), Value4=rexp(100,2))
  </code></pre>
  
  <p>Works for one column: </p>
  
  <pre><code>CustomData[order(CustomData$Value1, decreasing=FALSE), ]
  </code></pre>
  
  <p>How sort all the columns data in decreasing/increasing order in reasonable manner? Thx.</p>
  
  <p>I have also tried something like this as posted elsewhere, but doesn't work as stated. </p>
  
  <pre><code>CustomData[do.call(order, as.list(CustomData)),] 
  </code></pre>
