Hi, I would like to find out the coordinates of the intersection points of 2 density curves. I did a search but i didn't get any significant results. I really hope some of you have some ideas. here it is an example: set.seed(123) x1 <- rnorm(100, 1, 1) x2 <- rnorm(100, 0, 1) d1 <- density(x1) d2 <- density(x2) plot(d1, col = 2) lines(d2, col = 4)
Now i would like to know the coordinates of the intersection point. I did some "trial and error" and i come up with these .... (that means i did several vertical and horizontal lines through the graph until visually i "hit" the intersection point) abline(v = 0.35, lty = 2) abline(h = 0.34, lty = 2) I really appreciate any hints you may have, thanks so much, Monica _________________________________________________________________ Your E-mail and More On-the-Go.
