Aesthetics geom_errorbar understands the following aesthetics (required aesthetics are in bold): x ymax ymin alpha colour linetype size width Examples # Create a simple example dataset df # Because the bars This can include aesthetics whose values you want to set, not map. rather than a function of the alpha level. other parameters to pass to the plot function, e.g., typ="b" to draw lines, lty="dashed" to draw dashed lines Details Drawing the mean +/- a confidence interval is a frequently used function http://vealcine.com/error-bar/r-plot-error-bars-scatter-plot.php

See layer for more details. It's also a good habit to specify the upper bounds of your plot since the error bars are going to extend past the height of your bars.
