Hi, I would like to draw a box at each corner of lower 10% and upper 10% in the scatter plot on(0,1)*(0,1) to indicate the lower and upper tail. I hope somebody can help me. Here is my code: ## scatter plot plot(hume_uni[,2],beec_uni[,2], pch=19, xlab="Hume_uni", ylab="Beec_uni", col= "blue") title(main="Scatter plot of uniformised data of Hume and Beechworth", font.main= 4) abline(lm(hume_uni[,2]~beec_uni[,2]), col= "red"). Thank you so much fro any help given.
