This can result in unexpected behavior and will not be allowed in a future version of ggplot2.

Arguments x vector of numeric
yplus vector of y-axis values: the tops of the error bars. The normed means are calculated so that means of each between-subject group are the same. If you want y to represent counts of cases, use stat="bin" and don't map a variable to y. Default is to use range of y, yminus, and yplus.
Barplots using base R Let's start by viewing our dataframe: here we will be finding the mean miles per gallon by number of cylinders and number of gears. For example: dat <- read.table(header=TRUE, text=' id trial gender dv A 0 male 2 A 1 male cap the width of the little lines at the tops and bottoms of the error bars in units of the width of the plot. 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.
