entropy: 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 and the joint entropy.

Examples

# NOT RUN {
data(iris)
cl <- cutree(hclust(dist(iris[,-5])), 4)
entropy(cl,iris$Species)
# }
