stri_extract_words: Extract Words from a Text

Description

This function extracts all words from each string.

Usage

stri_extract_words(str, locale = NULL)

Arguments

str

character vector or an object coercible to

locale

NULL or "" for text boundary analysis following the conventions of the default locale, or a single string with locale identifier, see stringi-locale.

Value

• A list of character vectors is returned. Each string consists of a separate word. If there are no words or if a string is missing, a single NA is provided on output.

Details

Vectorized over str.

Just like in stri_locate_words, ICU's word BreakIterator iterator is used to locate word boundaries, and all non-word characters (UBRK_WORD_NONE rule status) are ignored.
