title: lty and lwd in standard R 3.02 not working?
body: <p>I don't not know what I am doing wrong. This is sooo simple, but nevertheless I have no idea where my mistake is:</p>
  
  <p>I have the following code:</p>
  
  <pre><code>x&lt;-seq(-3000,3000,length=1000)
  hx&lt;-dnorm(x,mean=0,sd=1392.857)
  
  plot(x,hx,lwd=3,lty=4,col="blue")
  </code></pre>
  
  <p>Which gives</p>
  
  <p><img src="https://i.stack.imgur.com/ygdLg.png" alt="t1"></p>
  
  <p>Then I code:</p>
  
  <pre><code>plot(x,hx,lwd=3,lty=1,col="blue")
  </code></pre>
  
  <p>And I get the same picture?</p>
  
  <p>Why is lty not working here? Same holds for lwd? R somehow does not recognize it?</p>
  
  <p>I had never a problem like this. I just downloaded the new R version, because my old crashed. Where is my mistake?</p>
  
  <p>EDIT:
  How can I get a thinner line? If I use lwd=1 it is still so fat (only a slight change)? R lines used to be very thin, normally I had to adjust lwd up? How can I get a thinner line?</p>
