Here is my favourite workaround, the advantage is that you do not need any extra packages. Not the answer you're looking for? There's got to be an easier way to do this, right? If you want y to represent counts of cases, use stat="bin" and don't map a variable to y. http://caribtechsxm.com/error-bars/r-line-plot-error-bars.php

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.
