## Entropy

### Description

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

### Usage

    entropy(c1, c2)

### Arguments

`c1` | a vector containing the labels of the first classification. Must be a vector of characters, integers, numerics, or a factor, but not a list.
`c2` | a vector containing the labels of the second classification.

### Value

a list with the two conditional entropies, the joint entropy and output of sortPairs.

### Examples

    data(iris)
    cl <- cutree(hclust(dist(iris[,-5])), 4)
    entropy(cl,iris$Species)
