Label lines in a plot

Question

I am plotting two lines using

plot(x, y, type = "l", color = "red")

and

points(x2, y2, type = "l", color = "blue")

I want to be able to add a label next to each line (instead of a legend). I am pretty sure it is possible using the package in http://directlabels.r-forge.r-project.org/.

Yet, I don't find an easy way of doing that.

Answer 1

Instead of using locator(), you could also just make the label coordinates a function of your data. For example, piggy backing on Roman's demo:

text(x=rep(max(x)+3, 2), y=c(mean(y), mean(y2)), pos=4, labels=c('black line', 'red line'))
