Arguments

true.labels	Factor or list of factors with true class labels
predicted.prob	Numeric vector or list of numeric vectors with predicted probabilities
n.bins	Integer: Number of windows to split the data into
bin.method	Character: "quantile" or "equidistant": Method to bin the estimated probabilities.
pos.class	Integer: Index of the positive class
main	Character: Main title
subtitle	Character: Subtitle, placed bottom right of plot
xlab	Character: x-axis label
ylab	Character: y-axis label
show.marginal.x	Logical: Add marginal plot of distribution of estimated probabilities
marginal.x.y	Numeric: Y position of marginal markers on x-axis
marginal.col	Color for marginal markers
marginal.size	Numeric: Size of marginal markers
mode	Character: "lines", "markers", "lines+markers": How to plot.
show.brier	Logical: If TRUE, add Brier scores to trace names.
theme	List or Character: Either the output of a ⁠theme_*()⁠ function or the name of a theme. Use themes() to get available theme names. Theme functions are of the form ⁠theme_<name>⁠.
filename	Character: Path to save output.
...	Additional arguments passed to dplot3_xy

# Plot the calibration curve of the original predictions
dplot3_calibration(
  true.labels = segment_logistic$Class,
  predicted.prob = segment_logistic$.pred_poor,
  n.bins = 10,
  pos.class = 2
)

# Plot the calibration curve of the calibrated predictions

  )$fitted.values,
