title: Plots with good resolution for printing and screen display
body: <p>I was making my plots using </p>
  
  <pre><code>dev.new(width=5.8, height=3) 
  par(mfrow=c(1,3),mar=c(1,1,2,1),oma=c(4,1,2,0),mgp=c(3, 0.5, 0)) 
  plot(...)
  </code></pre>
  
  <p>and coping and pasting them into  Microsoft Word. They look really good in Word (I tried different widths until I found one that worked well) but when I printed them they looked terrible. After some web searching I found the resolution for printing should be at least 300ppi. So after fiddling with widths and heights for an eternity I came out with code that makes the plots look the same size but with a better resolution:</p>
  
  <pre><code>png(file="mag_feb.png",width=1800,height=950,res=300)
  </code></pre>
  
  <p>They now look good when printed, but they don't look sharp at all in Word (on screen). Could it be a problem with size? Isn't there a way to make graphs that look good printed and on screen? I already spent hours with this and can't think of anything else to try, so any help will be very much appreciated!</p>
  
  <p>Thanks!</p>
