over_across_family: The over-across function family

In TimTeaFan/dplyover: Create columns by applying functions to vectors and/or columns in 'dplyr'

Description

dplyover extends dplyr's functionality by building a function family around dplyr::across().

The goal of this over-across function family is to provide a concise and uniform syntax which can be used to create columns by applying functions to vectors and / or sets of columns in dplyr. Ideally, this will improve our mental model so that it is easier to tackle problems where the solution is based on creating new columns.

The functions in the over-apply function family create columns by applying one or several functions to:

basic functions

• dplyr::across(): a set of columns

• over(): a vector (list or atomic vector)

variants

• over2() two vectors of the same length (pairwise)

• over2x() two vectors (nested)

• across2() two sets of columns (pairwise)

• across2x() two sets of columns (nested)

• crossover() a set of columns and a vector (nested)
