title: Plot a normal distribution in R with specific parameters
body: <p>I'd like to plot something like this:</p>
  
  <pre><code>plot(dnorm(mean=2),from=-3,to=3)
  </code></pre>
  
  <p>But it doesn't work as if you do:</p>
  
  <pre><code>plot(dnorm,from=-3,to=3)
  </code></pre>
  
  <p>what is the problem?</p>
