Description

This function makes a delta plot following Holland et al. (2002).

Usage

1
delta.plot(X, k = 20, plot = TRUE, which = 1:2)

Arguments

X

a distance matrix, may be an object of class “dist”.

k

an integer giving the number of intervals in the plot.

plot

a logical specifying whether to draw the delta plot (the default).

which

a numeric vector indicating which plots are done; 1: the histogram of the delta_q values, 2: the plot of the individual delta.bar values. By default, both plots are done.

Details

See Holland et al. (2002) for details and interpretation.

The computing time of this function is proportional to the fourth power of the number of observations (O(n^4)), so calculations may be very long with only a slight increase in sample size.

Value

This function returns invisibly a named list with two components:
