In kfre: Kidney Failure Risk Equation (KFRE) Tools

Plot ROC and Precision Recall curves for KFRE variants

Description

Draws ROC and PR curves for the selected models and horizons. When mode is "both", returns a list of ggplot objects. Otherwise, draws the plots and returns NULL invisibly.

Arguments

df	Data frame containing model probabilities and outcomes.
num_vars	Integer vector, KFRE model sizes to plot, any of 4, 6, 8.
fig_size	Numeric length 2, plot device width and height.
mode	Character, "both" to return plots, otherwise draw only.
image_path_png	Optional directory to save PNGs.
image_path_svg	Optional directory to save SVGs.
image_prefix	Optional filename prefix.
bbox_inches	Character, passed through when saving.
plot_type	Character, which plots to render.
save_plots	Logical, save plots to disk if TRUE.
show_years	Integer vector, horizons to show, any of 2, 5.
plot_combinations	Logical, if TRUE draw pairwise overlays.
show_subplots	Logical, arrange subplots when TRUE.
decimal_places	Integer digits for annotations.
open_new_device	Logical, open device before plotting.

Value

List of ggplot objects when mode == "both", else NULL.
