Hi

what do you want to achieve?

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))

Points are plotted as a small circles in blue, you can make the points 
bigger by let say cex=2

> abline(lm(NI~TOC,data=TOC_NI),col = "red",lwd=3)

red line is plotted according to linear model

> points(NI~TOC,data=TOC_NI,col='red',pch=1,size=3) 

all points are newly plotted as red circles (and possibly overplot the 
former ones). There is no size parameter for plot command, therefore it is 
ommited.

see
?plot.default and ?par for available options.

You maybe want cex=3 to get those new points as bigger circles.

Petr
