joint.entropy: Joint Entropy

In AnderEhu/sme:

Description

Joint Entropy

Usage

joint.entropy(x, y = NULL, file = "None")

Arguments

x	a vector, matrix, or data.frame.
y	a vector. y must be NULL if x is a matrix or a data.frame.
file	In case of x been a data.frame or matrix, represent the name of output file for saving joint entropy plot.

Value

In case of x been a data.frame or matrix, joint entropy of all variables/columns in x. Otherwise, joint entropy of x and y.

Examples

df <- data.frame("V1" = sample.int(2,5,replace=TRUE), "V2" =sample.int(2,5,replace=TRUE) , "V3" = sample.int(2,5,replace=TRUE), "V4" = sample.int(2,5,replace=TRUE),  "V5" = sample.int(2,5,replace=TRUE), "V6" = sample.int(2,5,replace=TRUE), "V7" = sample.int(2,5,replace=TRUE), "V8" = sample.int(2,5,replace=TRUE))
x <- sample.int(2, 5,replace=TRUE)
y <- sample.int(2, 5,replace=TRUE)
joint.entropy(df, file ="jointEntropy")
joint.entropy(x = x, y = y)
