title: mtext() to add horizontal y labels
body: <p>I know it is going to be quick and simple for some of you. I just want to have a horizontal y axis label using <code>mtext()</code>. It has to do with adj I guess, but I have been wasting the last 2 hours trying to figure it out...
  In the following examples, I just want the y-labels (myLab) to be horizontal and left justified.</p>
  
  <pre><code>myLab &lt;- c("aaaaaaa", "bb", "c")
  
  par(oma=c(0,10,0,0)) # make a large left maring for the labels
  
  plot(x=c(1:3),
       y=c(1:3),
       pch="|",
       lwd=3,
       tck=0.01,
       yaxt="n",
       ylab="",
       xlab="my legend",
       at= c(1:3),
       )
  
  
  mtext(text=myLab,
        side=2,
        outer = FALSE,
        at=c(1:3)
        )
  </code></pre>
  
  <p>I do not need to use <code>mtext()</code>. If you have a better alternative, please let me know.</p>
  
  <p>Thanks!</p>
