Various people in the world create a growing number of R packages and host them on Github. We present a simple example of using such packages: we install, activate and use the package edatools (EDA stands for Exploratory Data Analysis) created by Robert Kabacoff and hosted on Github.

> install.packages("remotes")
> remotes::install_github("rkabacoff/edatools") # install edatools from Github

This downloads the package from GitHub and installs it in your default R library. The package edatools has one main function called contents() that collects information about a data frame, and functions print() and plot() to display the results. See the example below.

> library(edatools)              # activate edatools
> df_info <- contents(happiness) # use edatools
> print(df_info)
