Boxplot with mean and standard deviation in ggPlot2 (plus Jitter)
When you create a boxplot in R, it automatically computes median, first and third quartile (“hinges“) and 95% confidence interval of median (“notches“).
But we would like to change the default values of boxplot graphics with the mean, the mean + standard deviation, the mean – S.D., the min and the max values.
Here is an example solved using ggplot2 package. Plus here are represented points (the single values) jittered horizontally.
