TOC_NI<-read.csv2("C:/Users/hilliges/Desktop/Master/Daten/Statistik/TOC-NI.csv",
sep=";", dec=",", encoding="UTF-8")
circ<-TOC_NI[order(TOC_NI$NI,decreasing=T),][1:4,]
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)
points(NI~TOC,data=TOC_NI,col='red',pch=1,size=3)  ## this line is coloring
all points because you're using TOC_NI still

points(NI~TOC,data=circ,col='red',pch=1,size=3)  ## now we're only plotting
the four points in circ.


sorry for the confusion.  however, in the future please provide a
reproducible data set along with your question so we can more easily help.
