[R] shading (fill) the area between two lines

[AbouEl-Makarim Aboueissa]

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
