In LukasWallrich/timesaveR: Functions to Accelerate (Academic) Data Analysis and Reporting

Get duplicated items from a vector

Description

This function takes a numeric or character vector and returns a vector of the unique elements that appear more than once - so a simple shortcut for unique(x[duplicated(x)]) that is particularly friendly in pipes

Usage

dupl_items(x)

Arguments

x	A numeric or character vector from which to identify duplicate elements.

Value

A vector containing unique elements that are duplicated in the original vector. Returns an empty vector if there are no duplicates.

Examples

dupl_items(c(1, 2, 3, 3, 4, 5, 5, 5))
# Output: 3 5
dupl_items(c(1, 2, 3, 4))
# Output: numeric(0)
