[R] putting legend outside ploting region

[Aleš Žiberna]

Hello!

I have created a plot and would like to put a legend in the top left corner
(above and left of plotting region), but non of the functions can plot there
(I tried 'legend', 'text', 'points', 'lines', 'mtext', 'axes',...).

I would be very grateful if someone could help me put something in that
corrner, with any fuction.

Thanks,
Ales Ziberna
