R – How to show corpus text in R tm package

corpusrtm

I'm completely new in R and tm package, so please excuse my stupid question 😉
How can I show the text of a plain text corpus in R tm package?

I've loaded a corpus with 323 plain text files in a corpus:

 src <- DirSource("Korpora/technologie")
corpus <- Corpus(src)

But when I call the corpus with:

corpus[[1]]

I always get some output like this instead of the corpus text itself:

<<PlainTextDocument>>
Metadata:  7
Content:  chars: 144
Content:  chars: 141
Content:  chars: 224
Content:  chars: 75
Content:  chars: 105

How can I show the text of the corpus?

Thanks!

UPDATE
Reproducible sample: I've tried it with the built-in sample text:

> data("crude")
> crude
<<VCorpus>>
Metadata:  corpus specific: 0, document level (indexed): 0
Content:  documents: 20
> crude[1]
<<VCorpus>>
Metadata:  corpus specific: 0, document level (indexed): 0
Content:  documents: 1
> crude[[1]]
<<PlainTextDocument>>
Metadata:  15
Content:  chars: 527

How can I print the text of the documents?

Best Solution

This works in mine, to print the content text, with latest version of tm,

corpus[[1]]$content

Note: More or less as suggested by Ricky in the previous comment. Sorry, I wanted to write comment, only my rep is only 25 (need min. of 50 rep to comment).
