## Hamming distance

### Description

The Hamming distance is the number of positions where the values are
different.

### Usage

hamming(x, y)

### Arguments

### Details

For vectors `x`

and `y`

, the Hamming distance is defined as

*d(x, y) = ∑_i [x_i \neq y_i],*

where the quantity in the brackets
is 1 if the elements are not equal, and zero if the elements are equal.
Relation to other definitions:

The `hamming()`

function in `scipy.spatial.distance`

divides the result by the vector length. Our function is equivalent to
the SciPy version multiplied by the vector length.

Equivalent to the `hamming`

calculator in Mothur for
presence/absence vectors.

### Value

The Hamming distance between `x`

and `y`

.
