HDD: Lexical diversity: HD-D (vocd-d)

Description

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

Usage

HDD(txt, rand.sample = 42, char = FALSE, ...)

Arguments

txt

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

rand.sample

An integer value, how many tokens should be assumed to be drawn for calculating HD-D.

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 HD-D, an idealized version of vocd-d (see McCarthy & Jarvis, 2007). In contrast to lex.div, which by default calculates all possible measures and their progressing characteristics, this function will only calculate the HD-D value, and characteristics are off by default.
