## Entropy

### Description

Description of the entropy function.

### Usage

```
entropy(a, b)
```

### Arguments

`a` |
a vector of classifications; this must be a vector of characters, integers, numerics, or a factor, but not a list. |

`b` |
a vector of classifications |

### Details

A function to compute the empirical entropy for two vectors of classifications and the joint entropy

### Value

a list of four objects:

`uv`

the joint entropy`u`

the conditional entropy of partition`a`

`v`

the conditional entropy of partition`b`

`sort_pairs`

the output from the sort_pairs function
