find_min_dists {Bioi}

For all points in matrix 1, return the distance to and index of the nearest point in matrix 2.

Description

Find the shortest distance between each point in one data set and the points in a second set.

This function determines the distance between every point in mOne and the nearest point in mTwo.

Usage

find_min_dists(mOne, mTwo)

Arguments

mOne

A numeric matrix where each row is a localization and each column is a spatial axis.

mTwo

A numeric matrix with the same number of columns as mOne.

Examples

# Generate random data.
set.seed(10)

mOne <- as.matrix(data.frame(
x = rnorm(10),
y = rbinom(10, 100, 0.5),
z = runif(10)
))

mTwo <- as.matrix(data.frame(
x = rnorm(20),
y = rbinom(20, 100, 0.5),
z = runif(20)
))

# Find the minimum distance between each point in mOne and the points in
# mTwo.
find_min_dists(mOne, mTwo)
