Plot 1:1 relationship
abline() takes the intercept and slope, which for a 1:1 relationship are 0 and 1, respectively. So: abline(0, 1) Sarah

Dear list, I am looking to plot a line on a graph to show the 1:1 relationship, in order to demonstrate the pattern i have observed is off the line, however i am unsure. I have tried abline but i can not see a function to plot the 1:1? Any help would be greatly appreciated #generate data y <- rnorm(30, mean=1.5, sd= 0.005) x <- rnorm(30, mean=1.5, sd= 0.005) plot(x,y) Thanks, Peter
