Calculate the Predicted Class from Probability Matrix

Source: R/performance.R
predicted_class.Rd

This function calculates the predicted class from a matrix of predicted probabilities. The class with the highest probability is selected as the predicted class.

Usage

predicted_class(prob)

Arguments

prob

A matrix of predicted probabilities with column names indicating the classes.

Value

A vector of predicted classes corresponding to the highest probability for each row in the input matrix.

Examples

prob <- matrix(c(0.2, 0.8,
                 0.6, 0.4),
               nrow = 2, byrow = TRUE,
               dimnames = list(NULL, c("A", "B")))
predicted_class(prob)
