Thanks Jim, that was I did to generate graphic from
plot(c(-4,0,4),c(0,1,1),type="s",xlab="x",ylab="y"),
it displayed [-4, -2,
0, 2, 4] in X, I tried to twist it, but could not get [-4, -3, -2, -1, 0,
1, 2, 3, 4] in X. Also, that the y 0.0 is above the X axis.
I guess I try to figure out if, in general, there are parameters to define
?x (i.e ?x= 1), and to define [0, 0.0] at the joint of x axis and y axis.
But never mind, if it is too much to ask :-).
Thank you and greatly appreciate kind responses.
