The EnvStats functions listed below create summary statistics and plots.
Summary Statistics
R comes with several functions for computing summary statistics, including
mean, var, median, range,
quantile, and summary. The following functions in
EnvStats complement these R functions.

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.
