Abstract: ngram extracts n-gram variables containing counts of how often the n-grams occur in a given text. An n-gram is an n-long sequence of words. For example, "sheep" is a unigram (1-gram), "black sheep" is a bigram (2-gram), and "the black sheep is happy" is a 5-gram. This is useful for text mining applications.
