The `text` function accepts the 'xpd' argument for `par`.

?par
?text

(Similar but not exactly the same as R-FAQ "7.27 How can I create  
rotated axis labels?")

I'm not sure what sort of "dirt" Uwe was expecting, but I'm guessing  
he meant that you probably were not going to be getting exactly what  
you wanted with the first attempt and were going to need to adjust the  
locations "by hand" after digging around in the par documentation.
