convert.confusion.matrix: Converts the position of any element of confusion matrix to VP, FP, FN, VN

Description

This function receives a confusion matrix and the matrix values to keep the order VP, FP, FN, VN.

Usage

convert.confusion.matrix(confusion.matrix, cm.position)

Arguments

confusion.matrix

is the confusion matrix to be converted.

cm.position

is the position of your VP, FP, FN, VN at the confusion matrix.

Value

a new confusion matrix
