)Either an object of class kRp.text,
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.
A vector or matrix (with exactly one column) which defines familiar words. For valid results the short Harris-Jacobson word list for grades 1 and 2 (english) should be used.
A numeric vector with named magic numbers, defining the relevant parameters for all formulas of the index.
A numeric vector with named magic numbers for the first of the formulas.
A numeric vector with named magic numbers for the second of the formulas.
A numeric vector with named magic numbers for the third of the formulas.
A numeric vector with named magic numbers for the fourth of the formulas.
A numeric vector with named magic numbers for the fifth of the formulas.
Further valid options for the main function,
see readability for details.
An object of class kRp.readability.
This function calculates the revised Harris-Jacobson readability formulas (1 to 5),
as described in their paper for the
18th Annual Meeting of the College Reading Association (Harris & Jacobson,
1974). In contrast to readability,
which by default calculates all possible indices,
this function will only calculate the index values.
This formula doesn't need syllable count.
