MTLD: Lexical diversity: Measure of Textual Lexical Diversity (MTLD)

Description

This is just a convenient wrapper function for lex.div.

Usage

MTLD(txt, factor.size = 0.72, char = FALSE, ...)

Arguments

txt

An object of either class kRp.tagged-class or kRp.analysis-class, containing the tagged text to be analyzed.

factor.size

A real number between 0 and 1, defining the MTLD factor size.

char

Logical, defining whether data for plotting characteristic curves should be calculated.

...

Further valid options for the main function, see lex.div for details.

Value

• An object of class kRp.TTR-class.

Details

This function calculates the measure of textual lexical diversity (MTLD; see McCarthy & Jarvis, 2010). In contrast to lex.div, which by default calculates all possible measures and their progressing characteristics, this function will only calculate the MTLD value, and characteristics are off by default.
