## Hamming distance

### Description

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

### Usage

```
hamming(x, y)
```

### Arguments

`x` , `y` |
Numeric vectors. |

### Details

For vectors `x`

and `y`

, the Hamming distance is defined as

`d(x, y) = \sum_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`

.
