no object in values - Githubissues

MIZUNOYUSUKE commented 7 years ago

I made tables with @koheiw's github (https://github.com/koheiw/IJTA/blob/master/documents/corpus.md) to learn how to use corpus. Although other process had complete successfully, I made an error when I tried to count how many objects in the values. The file named "data_corpus_asahi_2016" is exist.

corp_morning <- corpus_subset(data_corpus_asahi_2016, edition == '朝刊') # 朝刊だけを選択 ndoc(corp_morning)

To improve this situation, I confirmed that machine's default encoding and Rstudio's one were UTF-8 ran these commands below.

require(quanteda) # パッケージの読み込み
> txt <- readLines("data/asahi_head.txt")
> setwd('C:\\Users\\mizuno yusuke\\Downloads\\IJTA-master\\IJTA-master')
> load('data/data_corpus_asahi_2016.RData') # Rオブジェクトの読み込み
> table(docvars(corp, 'month'))

I worked under the environment below.

@MIZUNOYUSUKE 　報告ありがとうございます。エラーメッセージも投稿してもらえますか？

赤文字のエラーメッセージは出ませんでしたが、実行すると以下のようになりました。

> corp_morning <- corpus_subset(data_corpus_asahi_2016, edition == '朝刊') # 朝刊だけを選択
> ndoc(corp_morning)
[1] 0
> table(weekdays(docvars(corp_morning, 'date')))
< table of extent 0 >

Rコンソール上での入力がUTF-8になっていないことが考えられます。試しに以下のコマンドをコピーせず、タイプし、実行してみてください。

Encoding('朝刊')
Encoding('あいうえお')
