In funprog: Functional Programming

Description Main functions Helper functions purrr syntax

The funprog package implements in R some functions existing in other pure functional programming languages.

The package provides high-order functions, for example :

group_if, inspired by Haskell's groupBy
sort_by, inspired by Haskell's sortBy

Helper functions can be used in conjunction with the main functions :

%on% combines two functions into one and serves to create a predicate function to group_if
descending is used to reverse the output of a sorting function used with sort_by

`purrr` syntax

If the purrr package is installed, you can use its special syntax to create very compact anonymous functions, for example ~ abs(.x - .y) > 1 instead of function(x, y) abs(x - y) > 1.
