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)
z <- rbind(x,y)
rownames(z) <- c("Fred", "Tom")
hamming.distance(z)
hamming.distance(1:3, 3:1)
