stri_join_list: Concatenate Strings in a List

Description

These functions concatenate strings in each character vector in a given list. stri_c_list and stri_paste_list are aliases for stri_join_list.

Usage

stri_join_list(x, sep = "", collapse = NULL)
stri_c_list(x, sep = "", collapse = NULL)
stri_paste_list(x, sep = "", collapse = NULL)

Arguments

x

a list consisting of character vectors

sep

a single string; separates strings in each of the character vectors in x

collapse

a single string or NULL; an optional results separator

Value

Returns a character vector.

Details

Unless collapse is NULL, the result will be a single string. Otherwise, you get a character vector of length equal to the length of x.

Vectors in x of length 0 are silently ignored.

If collapse or sep has length greater than 1, then only the first string will be used.
