Dear All: I am trying to shade the area between the two lines; *line 1* and *line 2*.
The help page for polygon() gives some examples of this. Duncan Murdoch
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
