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)
