[R] Put 2 ablines in an "empty plot"

[Chel Hee Lee]

The following example may give you an idea regarding your question. 
Please see what happens by typing the codes

 > x <- seq(from=-5, to=5, by=1)
 > y1 <- 0 + 0.5*x
 > y2 <- 0 - 0.5*x
 >
 > plot(x,y1, type="n")
 > points(x,y1)
 > points(x,y2)
 > abline(a=0, b=0.5)
 > abline(a=0, b=-0.5)

Is this what you are looking for?  I hope this helps.
