Re: [R] colored outliers
Dear Petr and Justin, my problem ist, that I only want to have the 4 highest values for Ni as a red point or with a red circle. The other points should not be modificated. In your proposals always all points get a red circle or a red point not only the 4 highest Ni values! I hope you could understand me! Thanks for your help!

Re: [R] colored outliers
Hi Justin, it still does not work. All points become red. I use this skript with your modifications: 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(0,450)) abline(lm(NI~TOC,data=TOC_NI),col = red,lwd=3) points(NI~TOC,data=TOC_NI,col='red',pch=1,size=3) Maybe the the Sourcefile will help to solve the prob? http://r.789695.n4.nabble.com/file/n4291954/TOC-NI.csv TOC-NI.csv Thank you so muich!

Re: [R] colored outliers
Hi what do you want to achieve? Hi Justin, it still does not work. All points become red. I use this skript with your modifications: 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(0,450)) 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. Regards Petr Maybe the the Sourcefile will help to solve the prob? http://r.789695.n4.nabble.com/file/n4291954/TOC-NI.csv TOC-NI.csv Thank you so muich!

[R] colored outliers
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(0,450)) abline(lm(NI~TOC,data=TOC_NI),col = red,lwd=3) summary(lm(NI~TOC,data=TOC_NI)) The result is the following pic: http://r.789695.n4.nabble.com/file/n4282207/nickel_TOC_5f.png 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!

Re: [R] colored outliers
Hi Justin, thanks a lot for your quick answer. If I use your code, all points become red. How do you include the sorted and separated four values into the points argument? The variable in your script is called circ but this is not fronted up anymore. Here the script again: 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),] plot(NI~TOC,data=TOC_NI,col=blue, pch=16, xlim=c(0,450)) abline(lm(NI~TOC,data=TOC_NI),col = red,lwd=3) points(NI~TOC,data=TOC_NI,col='red',pch=1,size=3) Thanks a lot for your help!
