Split up a string into pieces.
Vectorised over string and pattern.
str_split(string, pattern, n = Inf, simplify = FALSE) str_split_fixed(string, pattern, n)
string |
Input vector. Either a character vector, or something coercible to one. |
pattern |
Pattern to look for. The default interpretation is a regular expression, as described
in stringi::stringi-search-regex. Control options with

number of pieces to return. Default (Inf) uses all possible split positions. For |

For str_split_fixed, a character matrix with n columns.
For str_split, a list of character vectors.
stri_split() for the underlying implementation.
