Join a character vector into an and/or list

Join a character vector into an and/or list

Usage

get_and_or_list(c_vector, conjunction = "and")

Arguments

c_vector

Character vector containing the list of words to be put in a list.

conjunction

The conjunction to be used as the connector. This is usually ‘and’ or ‘or’ with ‘and’ being the default.

Value

A character vector of length one containing a single correctly punctuated character string that lists each element in the first argument vector with commas between if there are more than two elements with the last two elements joined by the selected conjunction. A zero-length input returns an empty string and a single element is returned unchanged.

Examples

get_and_or_list(c("Bob", "John")) # "Bob and John"
#> [1] "Bob and John"
get_and_or_list(c("Bob", "John"), "or") # "Bob or John"
#> [1] "Bob or John"
get_and_or_list(c("Bob", "John", "Sam", "Bill"), "or")
#> [1] "Bob, John, Sam, or Bill"
# "Bob, John, Sam, or Bill"
