Lexical diversity: Moving-Average Type-Token Ratio (MATTR)
This is just a convenient wrapper function for lex.div.
MATTR(txt, window = 100, char = FALSE, ...)
txt |
An object of class |
window |
An integer value for MATTR, defining how many tokens the moving window should include. |
char |
Logical, defining whether data for plotting characteristic curves should be calculated. |

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.
An object of class kRp.TTR.
