lex.div.num

num.tokens

num.types

A character vector defining the measures to calculate.

measure

A numeric value defining the base of the logarithm. See <code><a rd-options="base:log" href="/link/log?package=koRpus&version=0.06-5&to=base%3Alog" data-mini-rdoc="base:log::log">log</a></code> for details.

log.base

Logical. If <code>FALSE</code>, short status messages will be shown.
<code>TRUE</code> will also suppress all potential warnings regarding the validation status of measures.

This function is a stripped down version of <code><a rd-options="koRpus:lex.div" href="/link/lex.div?package=koRpus&version=0.06-5&to=koRpus%3Alex.div" data-mini-rdoc="koRpus:lex.div::lex.div">lex.div</a></code>. It does not analyze text,
but takes the numbers of tokens and types directly to calculate measures for which this information is sufficient:
<ul>
<li> <code>"TTR"</code>The classic Type-Token Ratio
 </li>
<li> <code>"C"</code>Herdan's C
 </li>
<li> <code>"R"</code>Guiraud's Root TTR

<li> <code>"CTTR"</code>Carroll's Corrected TTR
 </li>
<li> <code>"U"</code>Dugast's Uber Index

A set of tools to analyze texts. Includes, amongst others,
functions for automatic language detection, hyphenation, several indices of
lexical diversity (e.g., type token ratio, HD-D/vocd-D, MTLD) and readability
(e.g., Flesch, SMOG, LIX, Dale-Chall). Basic import functions for language
corpora are also provided, to enable frequency analyses (supports Celex and
Leipzig Corpora Collection file formats) and measures like tf-idf. Support for
additional languages can be added on-the-fly or by plugin packages. Note: For
full functionality a local installation of TreeTagger is recommended. 'koRpus'
also includes a plugin for the R GUI and IDE RKWard, providing graphical dialogs
for its basic features. The respective R package 'rkward' cannot be installed
directly from a repository, as it is a part of RKWard. To make full use of this
feature, please install RKWard from https://rkward.kde.org (plugins are detected
automatically). Due to some restrictions on CRAN, the full package sources are
only available from the project homepage. To ask for help, report bugs, suggest
feature improvements, or discuss the global development of the package, please
subscribe to the koRpus-dev mailing list (https://ml06.ispgateway.de/mailman/
listinfo/korpus-dev_r.reaktanz.de).
