dist-matrix: Distance Matrix Computation from Two Matrices

Description

This function extends dist to accept two arguments.

Usage

distR(x1, x2 = NULL)

Arguments

x1

matrix of size N1 x n

x2

matrix of size N2 x n

Value

Matrix of size N1 x N2

Details

Computes the distances between the coordinates in x1 and the coordinates in x2. The matrices x1 and x2 do not need to have the same number of rows, but need to have the same number of columns (e.g., manifold dimensions).

Examples

# NOT RUN {
A <- matrix(rnorm(50),5,10)
D <- distR(A,A[-3,])
# }
