title: R fitting text on abline
body: <p>I want to place a text string on an fx. abline(0,0.2) </p>
  
  <p>But data is changing in scale (fx. 0,01-1 and 5-2000) in my for loop, so how to control the position of the text so it always sits nicely on the abline in the plot?</p>
  
  <p>(without the loop):</p>
  
  <pre><code>#example data row 1
  x1&lt;-1:10 
  y1&lt;-10:1
  
  plot(x1,y1)
  abline(0,0.2)
  text(?,?,"text",srt=0.2)
  </code></pre>
