distances {FRK}

Pre-configured distances

Description

Useful objects of class distance included in package.

Usage

measure(dist, dim)

Euclid_dist(dim = 2L)

gc_dist(R = NULL)

gc_dist_time(R = NULL)

Arguments

dist

a function taking two arguments x1,x2

dim

the dimension of the manifold (e.g., 2 for a plane)

R

great-circle radius

Details

Initialises an object of class measure which contains a function dist used for computing the distance between two points. Currently the Euclidean distance and the great-circle distance are included with FRK.

Examples

M1 <- measure(distR,2)
D <- distance(M1,matrix(rnorm(10),5,2))
