[R] text at the upper left corner outside of the plot region

[batholdy at googlemail.com]

Hi,

is there a way to place text at the upper left corner (or another  
corner) of the plot?

I want to place it really at the upper left corner of the whole plot  
(the file I get),
not at the upper left corner of the plot-region.



I tried text() and mtext(), and corner.label() of the plotrix package  
but it didn't work out.


thanks!
