I am beginner in R and i have a simple regression. Now i want to plot the equation of the regression line into the plot. The most easiest way. I already tried to get it done by following some ideas here.

DICE_Quartal<-read.csv("")
attach(DICE_Quartal)
plot(Preise.Fernbusmarkt ~ Auskunftpflichtige.Unternehmen) + abline(cor_preis_unternehmen, col = "red")

Please fix the question and ensure it asks for what you want and that any code in it is *reproducible* so that anyone else can run it. See the instructions at the top of [tag:r] . – G. Grothendieck Sep 11 '19 at 12:41
