>I do not know if I am clear enough. Anyway, thank you in advance. Suppose the upper limits are in U, the lower limits in L, and the x values in X. Then # set up the axes etc. plot(X, U, ylim=range(c(L,U)), type='n') segments(X, L, X, U) will do what you describe. You should also look at arrows(), in case you want points or crossbars on the ends of the segments.
