  <p>I'm trying to add a best fit normal over a histogram in R. Right now, I have the following:</p>
  
  <pre><code>x&lt;-table[table$position==1,]$rt
  hist(x,breaks=length(x))
  </code></pre>
  
  <p>And now I'd like to plot a normal curve over this plot which allows for skew and for kurtosis. How can I do this? This is what my curve looks like:</p>
