Thanks so much for the reply, Ista. I used "plotrix" library.

Here is my example:

xx <- seq(0.05, 0.95, by=0.05)
lower <- c(-2.896865, -2.728416, -2.642574, -2.587724, -2.548672, -2.518994,
-2.495409, -2.476031, -2.459662, -2.445513, -2.433014, -2.421739, -2.411344,
-2.401536, -2.392040, -2.382571, -2.372786, -2.362198, -2.349891)
upper <- c(2.311539, 2.372006, 2.423280, 2.469220, 2.511851, 2.552421,
 2.591797, 2.630657, 2.669579, 2.709135, 2.749928, 2.792670, 2.838268,
 2.887976, 2.943683, 3.008502, 3.088240, 3.195954, 3.373528)

library(plotrix)
plotCI(xx,ui=upper,li=lower,err="y",pch=NA, xlab="", ylab="", ylim=c(-5,
5),  slty="solid",scol="blue", lwd=2)


My question is how can I change the xllim to be c(0,1) which corresponds to
the "xx" values.
