A generic function to create a data structure for every variable pair in a dataset

Source: R/pairwise.R
pairwise.Rd

Creates a data structure for every variable pair in a dataset.

Usage

pairwise(x, score = NA_character_, pair_type = NA_character_)

# S3 method for class 'matrix'
pairwise(x, score = NA_character_, pair_type = NA_character_)

# S3 method for class 'data.frame'
pairwise(x, score = NA_character_, pair_type = NA_character_)

# S3 method for class 'easycorrelation'
pairwise(x, score = NA_character_, pair_type = NA_character_)

as.pairwise(x, score = NA_character_, pair_type = NA_character_)

Arguments

x

A dataframe or symmetric matrix.

score

a character string indicating the value of association, either "nn", "fn", "ff".

pair_type

a character string specifying the type of variable pair.

Value

A tbl_df of class pairwise for pairs of variables with a column value for the score value, score for a type of association value and pair_type for the type of variable pair.

Methods (by class)

  • pairwise(matrix): pairwise method

  • pairwise(data.frame): pairwise method

  • pairwise(easycorrelation): pairwise method

Functions

  • as.pairwise(): Same as pairwise
