Используя пакет text2vec, я создал словарь.text2vec: Итерация над лексикой после использования функции create_vocabulary
vocab = create_vocabulary(it_0, ngram = c(2L, 2L))
Vocab выглядит примерно так
> vocab
Number of docs: 120
0 stopwords: ...
ngram_min = 2; ngram_max = 2
Vocabulary:
terms terms_counts doc_counts
1: knight_severely 1 1
2: movie_expect 1 1
3: recommend_watching 1 1
4: nuke_entire 1 1
5: sense_keeping 1 1
---
14467: stand_idly 1 1
14468: officer_loyalty 1 1
14469: willingness_die 1 1
14470: fight_bane 3 3
14471: bane_beginning 1 1
Как я могу проверить диапазон terms_counts колонки? Мне это нужно, потому что это будет полезно для меня во время подрезки, который мой следующий шаг
pruned_vocab = prune_vocabulary(vocab, term_count_min = <BLANK>)
Ниже код воспроизводимая
