Details
Calculates the New Dale-Chall Readability Formula. In contrast to readability
,
which by default calculates all possible indices,
this function will only calculate the index value.
If parameters="PSK"
, the parameters by Powers-Sumner-Kearl (1958) are used, and if
parameters="old"
, the original parameters by Dale-Chall (1948), respectively.
This formula doesn't need syllable count.
Value
An object of class kRp.readability
.
