#' @title EvaluationMeasures.TPR
#' @description TPR of prediction
#' @details True Positive Rate is Proportional of positives that are correctly identified
#' @details By getting the predicted and real values or number of TP,TN,FP,FN return the True Positive Rate or Sensitivity or Recall of model
#' @author Babak Khorsand
#' @export EvaluationMeasures.TPR
#' @param Real Real binary values of the class
#' @param Predicted Predicted binary values of the class
#' @param TP Number of True Positives. Number of 1 in real which is 1 in predicted.
#' @param TN Number of True Negatives. Number of 0 in real which is 0 in predicted.
#' @param FP Number of False Positives. Number of 0 in real which is 1 in predicted.
#' @param FN Number of False Negatives. Number of 1 in real which is 0 in predicted.
#' @param Positive Consider 1 label as Positive Class unless changing this parameter to 0
