English function-word stop list

A small, fixed list of English function words (articles, prepositions, conjunctions, pronouns, auxiliaries) for the stop_words argument of text_hypergraph(). Deliberately minimal and versioned with the package: corpus-specific boilerplate (e.g. "study", "results" in an abstract corpus) should be added by the caller, as in c(stop_words_en(), "study", "results").

Usage

stop_words_en()

Value

A sorted character vector of lowercase English function words.
