Compute interval distance matrix

Dispatcher that computes a distance matrix using a named interval metric.

Usage

idist(centers, radii = NULL, metric = "Wasserstein")

Arguments

centers

Numeric matrix of interval midpoints (n x p), or an interval_data object.

radii

Numeric matrix of interval half-widths (n x p). Ignored if centers is an interval_data object.

metric

Character string: one of "Int-Euclidean", "Hausdorff", "Ichino-Yaguchi", or "Wasserstein".

Value

A symmetric n x n distance matrix.

Examples

C <- matrix(rnorm(12), 4, 3)
R <- matrix(runif(12, 0.1, 0.5), 4, 3)
D <- idist(C, R, "Wasserstein")
