Tidyverse
The tidyverse is a collection of open source R packages introduced by Hadley Wickham and his team that "share an underlying design philosophy, grammar, and data structures" of tidy data. The functions contain several uncharacteristic features in comparison to other R programming paradigms including , which allows for unquoted character strings in most functions, and consistently using data as the first argument, which allows for liberal use of the magrittr pipe function: %>%.
The core packages are ggplot2, , , , , , , and , which provide functionality to model, transform, and visualize data. As of November 2018, the tidyverse package and some of its individual packages make up 5 out of the top 10 most downloaded R packages, and are the subject of multiple books and papers. It has been criticised by Norman Matloff and Bob Muenchen.
