If your data needs to be restructured, see this page for more information. The method in Morey (2008) and Cousineau (2005) essentially normalizes the data to remove the between-subject variability and calculates the variance from this normalized data. # Use a consistent y Solution To make graphs with ggplot2, the data must be in a data frame, and in “long” (as opposed to wide) format.

If you want y to represent counts of cases, use stat="bin" and don't map a variable to y. Not quite a prerequisite: add the ability to have left/bottom (without top/right) axes It’s hard to get ggplot to draw left and bottom axes only.
