Check membership of first vector compared to other vectors

This is an internal helper function to check if elements of the first vector are subsets of one or more other vectors. Ordering of elements is ignored.

Usage

checkVectorContain(..., ignore_dups = FALSE)

Arguments

...

arguments of two or more vectors.

ignore_dups

logical scalar to disregard duplicate elements during comparison. Default is FALSE.

Value

a logical scalar

Examples

vec1 <- c("cherry", "apple", "cherry")
vec2 <- c("apple", "cherry", "banana", "cherry")
vec3 <- c("banana", "kiwi", "apple", "cherry")
vec4 <- c("banana", "apple", "apple", "cherry")

checkVectorContain(vec1, vec2, vec3, ignore_dups = TRUE)   # returns TRUE
#> [1] TRUE
checkVectorContain(vec1, vec2, vec4, ignore_dups = FALSE)  # returns FALSE
#> [1] TRUE
