(1) Plot the cumulative type/Token ratio in a text;
(2) Track the occurrence of a particular word in a text and plot all occurrences of the word in a dispersion plot;
(3) Show graphically the Relative frequency of the word across n equal sub-parts of the text and add to the plot chi-square and a dispersion measure (default is Juilland's D).
