Hi @ all,
I have question how to mark significant outliers in R.
This is my very simple script to plot a regression:
TOC_NI<-read.csv2("C:/Users/XYZ/Desktop/Master/Daten/Statistik/TOC-NI.csv",
sep=";", dec=",", encoding="UTF-8")
plot(NI~TOC,data=TOC_NI,col="blue", pch=16, xlim=c(0,4500000))
abline(lm(NI~TOC,data=TOC_NI),col = "red",lwd=3)
summary(lm(NI~TOC,data=TOC_NI))
The result is the following pic:

nickel_TOC_5f.png
Now I want to make small red circles around the four highest values of Ni.
Does anyone has an idea how to do that?
Thanks a lot!
Best Regards
Geophagus
