dist2All: Distances to all data points

In Mthrun/Distances: Functions For Different Distance Measures

Description

Calculates all distances from a given vector to the rows of a matrix.

Usage

dist2All(x, data, defined, distance)

Arguments

x	A vector containing the data point to be compared to data.
data	A matrix containing the data points to be compared with x.
defined	A vector of the same length as x and the rows of data, containing 1 for all columns of the data to be compared and any other value for columns to be discarded.
distance	A string marking, which distance measure is to be used. Euclidean by default.

Value

distToAll

A vector containing the distances from x to all rows of data.

Note

This function is very inefficient for large Data! For euclidean distance form a given vector to the rows of a matrix use dist2AllEuclid instead.
