title: Create summary statistics based on condition
body: <p>Normally to make summary statistics on a condition I would say </p>
  
  <pre><code>summary(data$how_fast[data$weight == 'Medium' &amp; data$height == 'High'], basic = T)
  </code></pre>
  
  <p>But what I would like is to output all of the summary statistics for every variable.</p>
  
  <pre><code>summary(data[data$weight == 'Medium' &amp; data$height == 'High'], basic = T)
  </code></pre>
  
  <p>So we'd get summary statistics not just for <code>$how_fast</code>, but also for other variable like <code>$start_speed</code> or <code>$medals</code>.</p>
  
  <p>Ideally, it'd be stored in a awesome table (although I believe you can do this using <code>rtf package</code>). </p>
