如何打印存储在 R 中 tm 语料库中的单个文档的文本表示? [英] How to print textual representation of single documents stored in a tm corpus in R?

问题描述

我使用的是 {tm} 包，然后使用

I was using {tm} package and then generated a corpus using

corpus = Corpus(VectorSource(sample.words))

然后我想检查语料库中的内容，但它打印了这个而不是它的文本:

then I want to check the content in corpus ,but it print this instead of its texts:

> corpus
<<VCorpus>>
Metadata:  corpus specific: 0, document level (indexed): 0
Content:  documents: 3933

现在我已经找到了一些查看语料库的方法，然后我开始想知道当一个对象被输入时R到底打印了什么?

Now I have found some methods to look into corpus,then I started wondering what exactly R print when an object was typed in ?

> class(corpus)
[1] "VCorpus" "Corpus" 
> typeof(corpus)
[1] "list"

为什么它不喜欢其他普通列表，打印其列和行?这与 class 属性有关吗?

Why it didn`t like other ordinary lists ,printing its columns and rows?Does this has something to do whit the class attribute?

我是 R 新手，不熟悉一些基本概念，感谢您的耐心等待！

I`m new in R and not familiar with some basic concepts, thanks for your patience!

推荐答案

tm 包的介绍文档说你可以使用，比如 writeLines(as.character(mycorpus[[4]])) 获取文档 4 的文本表示.

The introduction document to the tm package says that you can use , say, writeLines(as.character(mycorpus[[4]])) to get a textual representation of document 4.

您也可以使用content(myCorpus[[23]]).

要阅读介绍文档，请在 R 提示符下输入 browseVignettes() 并在将打开的浏览器窗口中搜索它.

To read the intro document, enter browseVignettes() on your R prompt and the search for it on the browser window that will have opened.
