Summary Plots
R comes with several functions for creating plots to summarize data, including hist, barplot, boxplot, dotchart, stripchart, and numerous others.

The help file Plotting Probability Distributions lists several EnvStats functions useful for producing summary plots as well.

In addition, the EnvStats function stripChart is a modification of stripchart that allows you to include summary statistics on the plot itself.

Finally, the help file Plotting Using ggplot2 lists several EnvStats functions for adding information to plots produced with the ggplot function, including the function geom_stripchart, which is an adaptation of the EnvStats function stripChart.
