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.
| Function Name | Description | 
| cv | Coefficient of variation | 
| geoMean | Geometric mean | 
| geoSD | Geometric standard deviation | 
| iqr | Interquartile range | 
| kurtosis | Kurtosis | 
| lMoment | \(L\)-moments | 
| pwMoment | Probability-weighted moments | 
| skewness | Skew | 
| summaryFull | Extensive summary statistics | 
| summaryStats | Summary statistics | 
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.
