pattern

the type of pattern matching: <code>"glob"</code> for 
"glob"-style wildcard expressions; <code>"regex"</code> for regular expressions;
or <code>"fixed"</code> for exact matching. See <a rd-options="" href="/link/valuetype?package=quanteda&version=0.99.22" data-mini-rdoc="quanteda::valuetype">valuetype</a> for details.

valuetype

ignore the case of dictionary values if <code>TRUE</code>

case_insensitive

concatenator that join multi-word expression in tokens object

concatenator

ignore single-word patterns if <code>TRUE</code>

remove_unigram

convert various input as pattern to a vector used in tokens_select, 
tokens_compound and kwic.

internal

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.
