Just to add to Uwe's good suggestion -- what I usually do is
opar <- par(no.readonly=TRUE)
Then pick legend co-ordinates, knowing that x and y on the plot canvas
now range from 0 to 1. For somewhere near the top-right corner...
par(opar) ## when done with the plot, to restore the co-ords.
Another choice is instead of the "par" calls...
and click on the plot where you want the legend.
Thirdly, the Hmisc package has a function largest.empty(), which can
find the "best" place to put a legend in a plot automagically.
