Thanks to Manuel and Ben for their responses. Getting the midpoints as indicated in the responses did the trick. Thanks for the help.

Vera, Ph.D. > University of South Florida, Dept of Surgery Assuming that you are asking about bargraph.CI from the sciplot package, and that you are trying to get x-axis tick-labels that are perpendicular to the x-axis, specifying las=2 in the call to bargraph.CI should work. If you want more control, you can assign the output of bargraph.CI to an object (a list that contains the x-values of the bars, summary stats, and CIs). This will allow you to position labels at the x-values of the plotted bars. For example: test <- bargraph.CI(x.factor = dose, response = len, data = ToothGrowth, xaxt="n") axis(side=1,at=test$xvals,labels=c("bar1","bar2","bar3"),las=2) -- Manuel A.
