Readability: Harris-Jacobson indices
This is just a convenient wrapper function for readability.
harris.jacobson( txt.file, word.list, parameters = c(char = 6), hj1 = c(dword = 0.094, asl = 0.168, const = 0.502), hj2 = c(dword = 0.14, asl = 0.153, const = 0.56), hj3 = c(asl = 0.158, lword = 0.055, const = 0.355), hj4 = c(dword = 0.07, asl = 0.125, lword = 0.037, const = 0.497), hj5 = c(dword = 0.118, asl = 0.134, lword = 0.032, const = 0.424), ... )

Either an object of class |
word.list |
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. |
parameters |
A numeric vector with named magic numbers, defining the relevant parameters for all formulas of the index. |
hj1 |
A numeric vector with named magic numbers for the first of the formulas. |
hj2 |
A numeric vector with named magic numbers for the second of the formulas. |
hj3 |
A numeric vector with named magic numbers for the third of the formulas. |
hj4 |
A numeric vector with named magic numbers for the fourth of the formulas. |
hj5 |
A numeric vector with named magic numbers for the fifth of the formulas. |

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.
