group_words(x, n, split = "\\s+", perl = TRUE, fixed = !perl,
  sep = " ", special = NULL, special_sep = "", trim_leading = TRUE,
  trim_trailing = trim_leading, tol = 0L, punct = TRUE)

`x`	Vector of strings to be split and regrouped
`n`	Number of characters per chunk of regrouped words
`split`	Pattern on which to split strings in ‘x’ into words
`perl`	TRUE if ‘split’ and ‘special_sep’ should be interpreted as perl-style regular expressions. Takes precedence over ‘fixed’
`fixed`	TRUE if ‘split’ and ‘special_sep’ should be interpreted as fixed strings
`sep`	Separator used when combining words into chunks
`special`	Pattern identifying words that should be combined in a special way (see Details)
`special_sep`	Separator used to combine two words if the first matches ‘special’
`trim_leading`	If TRUE, leading whitespace will be removed from chunks
`trim_trailing`	If TRUE, trailing whitespace will be removed from chunks
`tol`	Chunks will be allowed to be ‘tol’ characters longer than ‘n’ if that makes their lengths more even in overall
`punct`	If TRUE, words consisting of a single punctuation mark will always be merged to the previous chunk

The meaning of ‘word’ depends on the value of ‘split’. By default, strings are split on whitespace resulting in a list of words in the normal sense (maybe including some punctuation characters and the like). Clever choice of ‘split’, ‘sep’, ‘special’, and ‘special_sep’ let's you obtain a variety of effects (see wrap_lines).

A list of character vectors where every character vector contains one or more chunks of words. Every chunk contains from 1 to ‘n + tol’ characters unless it contains a single word of length > ‘n’ in which case its length is the length of the word.
