Compute confusion matrix to evaluate the accuracy of a classification.
Predicted labels vector, as returned by a classifier
Ground truth (correct) 0-1 labels vector
a table of Confusion Matrix
logreg <- glm(formula = vs ~ hp + wt,
family = binomial(link = "logit"), data = mtcars)
pred <- ifelse(logreg$fitted.values < 0.5, 0, 1)
ConfusionMatrix(y_pred = pred, y_true = mtcars$vs)
