...

Further valid options for the main function, see lex.div for details.

Details

This function calculates the moving-average type-token ratio (MATTR). In contrast to lex.div, which by default calculates all possible measures and their progressing characteristics, this function will only calculate the MATTR value.

Value

An object of class kRp.TTR-class.
