Get items that differ between x and y

Unlike setdiff, this function creates the union of x and y then removes values that are in the intersect, providing values that are unique to X and values that are unique to Y.

Usage

set_diff(x, y)

Arguments

x

a set of values.

y

a set of values.

Value

Unique values from X and Y, NULL if no unique values.

Examples

a <- 1:3
b <- 2:4

set_diff(a,b)
#> [1] 1 4
# returns 1,4

x <- 1:3
y <- 1:3

set_diff(x,y)
#> NULL
# returns NULL
