  combine_sep_ngram = function(x) attr(x[[1]], "sep_ngram"))

Arguments

...	vocabulary objects created with create_vocabulary.
combine_stopwords	function to combine stopwords from input vocabularies. By default we take a union of all stopwords.
combine_ngram	function to combine lower and upper boundary for n-grams from input vocabularies. Usually these values should be the same, so we take this parameter from first vocabulary.
