title: R: Format data frame summary
body: <p>Summary: control output format for <strong>summary(dataFrame)</strong> calls.</p>
  
  <p>Given data frame <strong>dataFrame</strong>, <strong>summary(dataFrame)</strong> creates an output which is easy to read only when the number of columns in <strong>dataFrame</strong> is small.</p>
  
  <p>Question:</p>
  
  <p>How to produce an output that contains 1 fact at a time?</p>
  
  <p>For example:</p>
  
  <pre><code>dataFrame  &lt;- data.frame(x=rnorm(100), y=rnorm(100), z=rnorm(100));
  summary(dataFrame);
  </code></pre>
  
  <p>gives:</p>
  
  <pre><code>       x                  y                  z          
   Min.   :-2.13427   Min.   :-2.12077   Min.   :-2.4453  
   1st Qu.:-0.53324   1st Qu.:-0.78915   1st Qu.:-0.4100  
   Median : 0.05675   Median :-0.22321   Median : 0.1356  
   Mean   : 0.09102   Mean   :-0.04939   Mean   : 0.1306  
   3rd Qu.: 0.69685   3rd Qu.: 0.58358   3rd Qu.: 0.7847  
   Max.   : 2.48204   Max.   : 2.65971   Max.   : 2.0504  
  </code></pre>
  
  <p>and the desired output would be:</p>
  
  <pre><code>      x          
  Min.   :-2.13427 
  1st Qu.:-0.53324 
  Median : 0.05675 
  Mean   : 0.09102 
  3rd Qu.: 0.69685 
  Max.   : 2.48204 
  
        y
  Min.   :-2.13427 
  1st Qu.:-0.53324 
  Median : 0.05675 
  Mean   : 0.09102 
  3rd Qu.: 0.69685 
  Max.   : 2.48204 
  
        z
  Min.   :-2.13427 
  1st Qu.:-0.53324 
  Median : 0.05675 
  Mean   : 0.09102 
  3rd Qu.: 0.69685 
  Max.   : 2.48204
