This function calculates the recall (also known as sensitivity) of a model based on the provided metrics and the true target values. Recall is defined as the ratio of true positive predictions to all actual positive instances (true positives + false negatives).

Usage

calculate_recall(metrics, target)

Arguments

metrics

A data frame with metrics obtained using get_sensitivity_specificity(), containing at least two columns: "Sensitivity" and "Specificity".

target

A character vector containing the true values from the target variable. It should have the same length as the predictions.

Value

A numeric vector representing the recall values. Recall is the fraction of actual positive instances that were correctly predicted.
