LDA $新モデルコンストラクタtext2vec Rパッケージエラー：.subset2でエラーが発生しました（public_bind_env、 "初期化"）（...）：未使用の引数（...）

Question

エラーは次のとおりです。

> lda_model = LDA$new(n_topics = 3, vocabulary = vocab, doc_topic_prior = 0.1, topic_word_prior = 0.01) 
Error in .subset2(public_bind_env, "initialize")(...) :

私は」語彙の後にLDA$newを実行するとエラーが発生しました。tokenizerとdtmは正常に作成されました。完全なコードは次のとおりです。

current_dir_files = list.files(path = ".", full.names = TRUE) 
files_iterator = ifiles(current_dir_files, reader = read_file) 
it_tokens <- itoken(files_iterator, preprocess_function = tolower, 
        tokenizer = word_tokenizer, progressbar = TRUE) 
vocab <- create_vocabulary(it_tokens, stopwords = words.remove) %>% 
    prune_vocabulary(term_count_min = 200, doc_proportion_max = 0.1) 

vec <- vocab_vectorizer(vocabulary = vocab) 

dtm <- create_dtm(it = it_tokens, vectorizer = vec) 

lda_model = LDA$new(n_topics = 3, vocabulary = vocab, doc_topic_prior = 0.1, topic_word_prior = 0.01) 

私が使用している「text2vec」バージョン0.5.0、3.4.1 R 64-ビット、RStudio 1.0.153。

ドキュメント - ?LDAとhttp://text2vec.org/topic_modeling.html#latent_dirichlet_allocationを確認してください。関数の署名がtext2vec 0.4以降に変更されました。今はvocabulary引数ではありません。
