compute_mattr

a <a rd-options="" href="/link/tokens?package=quanteda&version=1.5.2" data-mini-rdoc="quanteda::tokens">tokens</a> object

integer; the size of the moving window for computation of
TTR, between 1 and the number of tokens of the document

MATTR_window

From a tokens object, computes the Moving-Average Type-Token Ratio (MATTR)
from Covington &amp; McFall (2010), averaging all of the sequential moving
windows of tokens of size <code>MATTR_window</code> across the text, returning the
average as the MATTR.

lexdiv

A fast, flexible, and comprehensive framework for
quantitative text analysis in R.  Provides functionality for corpus management,
creating and manipulating tokens and ngrams, 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.
