By creating an object to hold your bar plot, you capture the midpoints of the bars along the abscissa that can later be used to plot the error bars. Scatter Plot With Error Bars In R PLAIN TEXT R: y **<- rnorm(500,** mean=1) y <- matrix(y,100,5) y.means <- apply(y,2,mean) y.sd <- apply(y,2,sd) http://datascienceplus.com/building-barplots-with-error-bars/ This can include aesthetics whose values you want to set, not map.

This can result in unexpected behavior and will not be allowed in a future version of ggplot2. Only needs to be set at the layer level if you are overriding the plot defaults.
