The graph of individual data shows that there is a consistent trend for the within-subjects variable condition, but this would not necessarily be revealed by taking the regular standard errors (or Error Bars In R The normed means are calculated so that means of each between-subject group are the same. This can result in unexpected behavior and will not be allowed in a future version of ggplot2.
