distanceNumericLevenshtein {CEGO}

Levenshtein Distance for Numeric Vectors

Description

Levenshtein distance for two numeric vectors, e.g., bit vectors.

Usage

distanceNumericLevenshtein(x, y)

Arguments

x

first vector (numeric)

y

second vector (numeric)

Value

numeric distance value

d(x,y)

, scaled to values between 0 and 1

Examples

#e.g., used for distance between bit strings
x <- c(0,1,0,1,0)
y <- c(1,1,0,0,1)
distanceNumericLevenshtein(x,y)
p <- replicate(10,sample(c(0,1),5,replace=TRUE),simplify=FALSE)
distanceMatrix(p,distanceNumericLevenshtein)
