epi_clean_get_dups: Get all duplicated rows including the originals

In AntonioJBT/episcout: Quickly Clean, Explore and Visualise Large Epidemiological Datasets

Get all duplicated rows including the originals

Description

base R duplicated() does not return the originals (duplicated - 1). See for example find duplicates in R.

Usage

epi_clean_get_dups(df = NULL, var = "", freq = 1)

Arguments

df	A data.frame to extract duplicates from
var	Variable/column name as a string to use to detect duplicate values
freq	Frequency count, an integer. Defaults to 1 (so will return original plus any repeating values)

Value

a data.frame with original and duplicated rows

Note

Creates a table with frequencies, checks those which have more than 1 (or value passed to freq and considers these as variables with duplicates) and extracts them.
