I want to add the lines between the reggression line and the points in the figure but I don't find a solution.
This is my currently plot
zz_fm <-lm(x ~ y)
plot(y,x, xlim = c(0,100),ylim=c(0,110))
abline(zz_fm, col ="green")
Can someone help me?

Relevant post? https://stats.stackexchange.com/questions/53254/how-to-find-residuals-and-plot-them What is the expected output? – zx8754 Oct 09 '17 at 11:43

1Try plot(y,x, xlim = c(0,100),ylim=c(0,110)) abline(resid(zz_fm), col ="green") – Aleksandr Oct 09 '17 at 11:46

What for? you make regression so you can plot fitted values over residuals. You see residuals on your plot as a distance between the line and the point. – Mateusz1981 Oct 09 '17 at 11:49

Linked Q is not an _exact_ duplicate, but the stats.SE link is a duplicate. take your pick – MichaelChirico Oct 09 '17 at 11:56

@Aleksandr, your solution doesn't work. I don't know if it's clear what I want. I want to plot the lines between the reggression line and the points – Tim Wendt Oct 09 '17 at 12:17
