def str_wrap(arr, width, **kwargs):
    r"""
    Wrap long strings in the Series/Index to be formatted in
    paragraphs with length less than a given width.

    This method has the same keyword parameters and defaults as
    :class:`textwrap.TextWrapper`.

    Parameters
    ----------
    width : int
        Maximum line width.
    expand_tabs : bool, optional
        If True, tab characters will be expanded to spaces (default: True).
    replace_whitespace : bool, optional
        If True, each whitespace character (as defined by string.whitespace)
        remaining after tab expansion will be replaced by a single space
        (default: True).
    drop_whitespace : bool, optional
        If True, whitespace that, after wrapping, happens to end up at the
        beginning or end of a line is dropped (default: True).
    break_long_words : bool, optional
        If True, then words longer than width will be broken in order to ensure
        that no lines are longer than width. If it is false, long words will
        not be broken, and some lines may be longer than width (default: True).
    break_on_hyphens : bool, optional
        If True, wrapping will occur preferably on whitespace and right after
        hyphens in compound words, as it is customary in English. If false,
        only whitespaces will be considered as potentially good places for line
        breaks, but you need to set break_long_words to false if you want truly
        insecable words (default: True).

    Returns
    -------
    Series or Index

    Notes
    -----
    Internally, this method uses a :class:`textwrap.TextWrapper` instance with
    default settings. To achieve behavior matching R's stringr library str_wrap
    function, use the arguments:

    - expand_tabs = False
    - replace_whitespace = True
    - drop_whitespace = True
    - break_long_words = False
    - break_on_hyphens = False

    Examples
    --------

    >>> s = pd.Series(['line to be wrapped', 'another line to be wrapped'])
    >>> s.str.wrap(12)
    0             line to be\nwrapped
    1    another line\nto be\nwrapped
    dtype: object

    kwargs['width'] = width

    tw = textwrap.TextWrapper(**kwargs)

    return _na_map(lambda s: '\n'.join(tw.wrap(s)), arr)
