`sep` | A string. The separator for pasting `string` elements together.

### Details

Elements that don't exist e.g. element 5 of `"abc"` are ignored.

### Value

A character vector.

### See Also

Other single element extractors: `str_elems()`, `str_elem()`

### Examples

    string <- c("abc", "def", "ghi", "vwxyz")
    str_paste_elems(string, 1:2)
    str_paste_elems(string, c(1, 2, 3, 4, -1))
