koRpus (version 0.04-40)

An R Package for Text Analysis

Description

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). #' Note: For full functionality a local installation of TreeTagger is recommended. Be encouraged to send feedback to the author(s)!
