title: How to change the distance between categorical ticks in ggplot2?
body: <p>I am using <code>coord_flip()</code> to make a forest plot.</p>
  
  <pre><code>df &lt;- data.frame(f1=factor(rbinom(100, 1, 0.45), label=c("m","w")),          
     f2=factor(rbinom(100, 1, 0.45), label=c("young","old")),
               boxthis1=rnorm(100), boxthis2=rnorm(100), boxthis3=rnorm(100))
  
  ggplot(aes(ymin = boxthis1, y=boxthis2,ymax=boxthis3, x = f1), data = df) + 
     geom_pointrange(size=0.5) +coord_flip()
  </code></pre>
  
  <p>How can I make it so that there is more distance between the two plots/ axis labels on the VERTICAL axis?</p>
