See these papers for a more detailed treatment of the issues involved in error bars with within-subjects variables. Furthermore, it's easy to graph asymmetrical error bars. http://waspsoft.com/error-bars/bar-chart-error-bars-r.html

error = z * s / sqrt(n) = 1.96 * s / sqrt(n) The underlying math is not trivial. Let's add them to the plot. >errbar(bp[,1], heights, upper, lower, add=T, xlab="") The paramerter add=T is important. I've spent all the afternoon with this graph until read this! However, when there are within-subjects variables (repeated measures), plotting the standard error or regular confidence intervals may be misleading for making inferences about differences between conditions.

If you want y to represent values in the data, use stat="identity". Here we start by specifying the dodge (the spacing between bars) as well as the upper and lower limits of the x and y axes.
