Description

This is just a convenient wrapper function for readability.

Usage

coleman.liau(txt.file, ecp = c(const = 141.8401, char = 0.21459, sntc =
  1.079812), grade = c(ecp = -27.4004, const = 23.06395), short = c(awl =
  5.88, spw = 29.6, const = 15.8), ...)

Arguments

txt.file

Either an object of class kRp.tagged-class, a character vector which must be be a valid path to a file containing the text to be analyzed, or a list of text features. If the latter, calculation is done by readability.num.

ecp

A numeric vector with named magic numbers, defining the relevant parameters for the cloze percentage estimate.

grade

A numeric vector with named magic numbers, defining the relevant parameters to calculate grade equvalent for ECP values.

short

A numeric vector with named magic numbers, defining the relevant parameters for the short form of the formula.

...

Further valid options for the main function, see readability for details.

Value

An object of class kRp.readability-class.

Details

This formula doesn't need syllable count.
