y_true: Ground truth (correct) labels vector
y_pred: Predicted labels vector, as returned by a classifier
labels: An optional vector containing the list of the existent (unique) labels.

Value

Recall (micro averaged)

Examples

labels <- c("Q1", "Q2", "Q3", "Q4")
truth <- sample(labels, 10, replace = TRUE)
pred <- sample(labels, 10, replace = TRUE)
Recall_micro(y_pred = pred, y_true = truth, labels)
