This is just a convenient wrapper function for readability.

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-class.
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.
