Details

Calculates the Spache Formula. In contrast to readability, which by default calculates all possible indices, this function will only calculate the index value.

By default the revised Spache formula is calculated. If parameters="old", the original parameters are used.

This formula doesn't need syllable count.

Examples

spache(tagged.text, word.list=spache.revised.wl)
