Please look at the labcurve function in the Hmisc package. Here is one line
from the documentation of ?labcurve
For automatic positioning of labels or keys, a curve is labeled at a point
that
is maximally separated from all of the other curves.
As you, the documentation uses the same words you do.
If you don't have it yet:
install.packages("Hmisc")
library("Hmisc")
?labcurve
