Examples

library(dplyr)

# Generate data for the example
heartfailure2 <- heartfailure
heartfailure2[sample(seq(NROW(heartfailure2)), 5), "creatinine"] <- NA

# optimal binning
bin <- binning_by(heartfailure2, "death_event", "creatinine")
bin

# summary optimal_bins class
summary(bin)

# performance table
attr(bin, "performance")

# extract binned results
if (!is.null(bin)) {
