Dear All:
I am trying to shade the area between the two lines; *line 1* and *line 2*. You can use this code as an example. x100<-c(-1,1,2,3,4,5,6,3) y100<-c(4,5,3,1,4,4,2,-1) plot(x100,y100) *##### line1* abline(a=-(Beta0-1)/Beta[1,2], b=-Beta[1,1]/Beta[1,2], lwd = 3, col="skyblue", lty=3) ##### lty=3, *##### line 2* abline(a=-(Beta0+1)/Beta[1,2], b=-Beta[1,1]/Beta[1,2], lwd = 3, col="skyblue", lty=3) ##### lty=3, thank you very much for your help with thanks abou ______________________ *AbouEl-Makarim Aboueissa, PhD* *Professor of Statistics* *Department of Mathematics and Statistics* *University of Southern Maine* [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
