Details
Calculates the Farr-Jenkins-Paterson index, a simplified version of Flesch Reading Ease. In contrast to readability, which by default calculates all possible indices, this function will only calculate the index value.
If parameters="PSK", the revised parameters by Powers-Sumner-Kearl (1958) are used.
Examples
## Not run:farr.jenkins.paterson(tagged.text)## End(Not run)
