Extract Unique Values from Each Column

Given a tibble or data.frame extract unique examples for each column. This function is not publically available, but maybe a future version will be.

Usage

extract.unique(dataset, cell.blank.tf, cell.NA.tf, size = 3)

Arguments

dataset

tibble or data.frame of interest

cell.blank.tf

constructed within dataset.summary() using the command purrr::map_dfc(dataset, is.BLANK) and returns a tibble the same dimensions as dataset and indicates whether or not each cell is blank. TRUE indicates the cell is blank and FALSE indicates it contains some type of value. NAs are dplyr::coalesce()d into FALSE.

cell.NA.tf

constructed within dataset.summary() using the command purrr::map_dfc(dataset, is.na) and returns a tibble the same dimensions as dataset and indicates whether or not each cell is blank. TRUE indicates the cell contains a NA and FALSE indicates it contains some type of value.

size

integer value indicating the number examples to return

Value

tibble of examples
