internal

A fast, flexible, and comprehensive framework for
quantitative text analysis in R.  Provides functionality for corpus management,
creating and manipulating tokens and n-grams, exploring keywords in context,
forming and manipulating sparse matrices
of documents by features and feature co-occurrences, analyzing keywords, computing feature similarities and
distances, applying content dictionaries, applying supervised and unsupervised machine learning,
visually representing text and text analyses, and more.

head.dfm function

<dl><dt>x</dt>
<dd>a dfm object</dd>
<dt>n</dt>
<dd>an integer vector of length up to <code>dim(x)</code> (or 1,
 for non-dimensioned objects). A <code>logical</code> is silently coerced to
 integer. Values specify the indices to be
 selected in the corresponding dimension (or along the length) of the
 object. A positive value of <code>n[i]</code> includes the first/last
 <code>n[i]</code> indices in that dimension, while a negative value
 excludes the last/first <code>abs(n[i])</code>, including all remaining
 indices. <code>NA</code> or non-specified values (when <code>length(n) &lt;
 length(dim(x))</code>) select all indices in that dimension. Must
 contain at least one non-missing value.</dd>
<dt>...</dt>
<dd>arguments to be passed to or from other methods.</dd></dl>
