<h2>Methods for Function meta in Package &lsquo;tm&rsquo;</h2>


<h3>Description</h3>

<p>
Methods for function <code>meta</code> in package <span class="pkg">tm</span>.
</p>


<h3>Methods</h3>

<dl>
<dt>object = "TextDocument"</dt><dd>If no <code>tag</code> is given, this
method pretty prints all <code>object</code>'s meta data. If <code>tag</code>
is provided its value in the meta data is returned.</dd>
<dt>object = "Corpus"</dt><dd>If no <code>tag</code> is given, this
method investigates the <code>type</code> argument. <code>type</code> must be
either <code>indexed</code> (default) or <code>corpus</code>. Former is a
shortcut for accessing document level meta data
(<code><a href="TextDocCol-class.html">DMetaData</a></code>) stored at the collection level (because
it forms an own entity, or for performance reasons, i.e., a form
of indexing, hence the name indexed), the latter a shortcut for
collection (corpus) specific meta data
(<code><a href="TextDocCol-class.html">CMetaData</a></code>). Depending whether a tag is set or not,
all or only the meta data identified by the tag is displayed or
modified.</dd>
<dt>object = "TextRepository"</dt><dd>If no <code>tag</code> is given, this
method pretty prints all <code>object</code>'s meta data. If <code>tag</code>
is provided its value in the meta data is returned.</dd>
</dl>

<h3>Examples</h3>

<pre>
data("crude")
meta(crude[[1]])
meta(crude[[1]], tag = "Topics")
meta(crude[[1]], tag = "Comment") &lt;- "A short comment."
meta(crude[[1]])
meta(crude)
meta(crude, type = "corpus")
meta(crude, "labels") &lt;- 21:40
meta(crude)
