stopwords: Stop Words

Description

Get a list of common function words (‘stop’ words).

Usage

stopwords(kind = "english")

Arguments

kind

a character vector giving the desired name or names of the stop word list(s), NA, or NULL. Allowed values are "danish", "dutch", "english", "finnish", "french", "german", "hungarian", "italian", "norwegian", "portuguese", and "russian"; these values retrieve the language-specific stop word lists compiled by the Snowball stemming project.

Value

A character vector of unique stop words of the specified kind (or kinds if kind is a vector), or NULL if kind = NULL.

Details

stopwords returns a character vector of case-folded ‘stop’ words. These are common function words that often get discarded before performing other text analysis tasks.

The built-in word lists returned by this function are reasonable defaults, but they may require further tailoring to suit your particular task.
