## Text Documents

### Description

Representing and computing on text documents.

### Details

Text documents are documents containing (natural language) text. The tm package employs the infrastructure provided by package NLP and represents text documents via the virtual S3 class `TextDocument`. Actual S3 text document classes then extend the virtual base class (such as `PlainTextDocument`).

All extension classes must provide an `as.character` method which extracts the natural language text in documents of the respective classes in a “suitable” (not necessarily structured) form, as well as `content` and `meta` methods for accessing the (possibly raw) document content and metadata.
