setdiff_all: Get the difference of two vectors in both directions.

In miracum/misc-diztools: Lightweight Utilities for 'DIZ' R Package Development

Get the difference of two vectors in both directions.

Description

The base-R function 'setdiff' is asymmetric meaning 'setdiff(vec1, vec2)' is not the same as 'setdiff(vec2, vec1)'. Only the first vector will be compared to the second vector and all elements not contained in the second are in the resulting vector. So if you also want in include all elements being in the second vector but not in the first, you can use this function. In this case you are searching for elements being in the union of both vectors but not in the intersect of both vectors. This function is a symmetric function. It doesn't matter in which order you input the vectors, the content will be the same. Only the order of the elements inside the output differs.

Usage

setdiff_all(vec1, vec2)

Arguments

vec1	First vector
vec2	Second vector

Value

The difference between both vectors.

Examples

## Not run: 
vec1 <- c(1,2,3,4)
vec2 <- c(3,4,5,6)
# setdiff(vec1, vec2) = c(1,2)
# setdiff(vec2, vec1) = c(5,6)
# setdiff_all(vec1, vec2) = c(1,2,5,6)
# setdiff_all(vec2, vec1) = c(5,6,1,2)

## End(Not run)
