Hamming Distances of Vectors

If both x and y are vectors, hamming.distance returns the Hamming distance (number of different elements) between this two vectors. If x is a matrix, the Hamming distances between the rows of x are computed and y is ignored.

Usage

hamming.distance(x, y)

Arguments

x

a vector or matrix.

y

an optional vector.

Examples

x <- c(1, 0, 0)
y <- c(1, 0, 1)
hamming.distance(x, y)
#> [1] 1
z <- rbind(x,y)
rownames(z) <- c("Fred", "Tom")
hamming.distance(z)
#>      Fred Tom
#> Fred    0   1
#> Tom     1   0

hamming.distance(1:3, 3:1)
#> [1] 2
