plot_cross_appl

Description

The heatmap indicating ML performance (e.g., MAE) in the self-validation and cross-applications.

Usage

plot_cross_appl(
  cross_appl_res,
  metric = "MAE",
  outdir = NULL,
  plot_width = 8,
  plot_height = 7
)

Arguments

cross_appl_res	The output object from rf_clf.cross_appl or rf_reg.cross_appl.
metric	The classification performance metric applied.
outdir	The outputh directory, default is NULL.
plot_width	The width (inches) of heatmap
plot_height	The height (inches) of heatmap.

Value

A heat map showing ML performance in self-validation and cross-applications.
