In specif: Word Specificity

Description

Utility functions to play with specificities.

Usage

	specif_calc(parts, data, token="peuple", method="base")
	specif_value(N, n, K, k, method="base")
	specif_cdf(parts, data, token="peuple", R=10, new=TRUE, method="base", ...)
	specif_cdmo(parts, data, token="peuple")
	specif_density(parts, data, token="peuple", R=10, new=TRUE, ...)
	specif_mode2cdf(data, maxi=sum(data), token="peuple", ...)
	specif_mode2density(data, maxi=sum(data), token="peuple", ...)
	specif_plot(d, data, token="peuple", R=NULL, method="base", ...) 

Arguments

new	if TRUE start a new window device
method	method used to calculate the specificity
...	other arguments passed to plot functions
N	number of balls in the urn
K	number of white balls in the urn
n	number of balls drawn from the urn
