HohgantR

The goal of HohgantR is to serve as a toolbox filled with all the miscellaneous functions that might be useful one day, or not…

Installation

You can install the latest version of HohgantR from GitHub with:

# install.packages("devtools")
devtools::install_github("BBieri/HohgantR")

A release on CRAN is not planned as the package is intended to serve as a “cabinet de curiosités” of R functions.

Slope charts à la Tufte
