Mutual information

1	mutual.information(x, y = NULL, file = "None")

`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 mutual information plot.

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

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)
mutual.information(df, file ="mutualInformation")
mutual.information(x = x, y = y)
