I would like to figure out a better way to label the horizontal abline.
I tried multiplying the text y position by a scale, but this didn't always put
the text in a useful position. I guess I am curious if there is a preferred
procedure for labeling the abline. Is there a way to "fill" the text label and
also put a box around the text label? I guess I would also like to have the
box around the text match the abline format.
Thank you for any info or insights.
x_vals<-1:1000
y_vals<-rnorm(1000)
plot(x_vals, y_vals)
top_label<-paste("Top Label = ", format(max(y_vals), digits=2), sep="")
abline(h=max(y_vals), col="darkred")
text(max(x_vals), max(y_vals), top_label, pos=2)
bottom_label<-paste("Bottom Label = ", format(min(y_vals),digits=2), sep="")
abline(h=min(y_vals), col="darkred")
text(max(x_vals), min(y_vals), bottom_label, pos=2)
