plot.performance_bin: Visualize Performance for an "performance_bin" Object

Description

It generates plots for understand frequency, WoE by bins using performance_bin.

Usage

# S3 method for performance_bin
plot(x, typographic = TRUE, ...)

Arguments

x

an object of class "performance_bin", usually, a result of a call to performance_bin().

typographic

logical. Whether to apply focuses on typographic elements to ggplot2 visualization. The default is TRUE. if TRUE provides a base theme that focuses on typographic elements using hrbrthemes package.

...

further arguments to be passed from or to other methods.

Examples

# NOT RUN {
# Generate data for the example
heartfailure2 <- heartfailure

set.seed(123)
heartfailure2[sample(seq(NROW(heartfailure2)), 5), "creatinine"] <- NA

# Change the target variable to 0(negative) and 1(positive).
heartfailure2$death_event_2 <- ifelse(heartfailure2$death_event %in% "Yes", 1, 0)

# Binnig from creatinine to platelets_bin.
breaks <- c(0,  1,  2, 10)
heartfailure2$creatinine_bin <- cut(heartfailure2$creatinine, breaks)

# Diagnose performance binned variable
perf <- performance_bin(heartfailure2$death_event_2, heartfailure2$creatinine_bin) 
perf
summary(perf)

plot(perf)

# Diagnose performance binned variable without NA
perf <- performance_bin(heartfailure2$death_event_2, heartfailure2$creatinine_bin, na.rm = TRUE) 
perf
summary(perf)

plot(perf)
plot(perf, typographic = FALSE)
