Plot ROC and Precision Recall curves for KFRE variants
Source:R/plot_kfre_metrics-doc.R
      plot_kfre_metrics.RdDraws 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.

- plot_combinations
 Logical, if TRUE draw pairwise overlays.
- show_subplots
 Logical, arrange subplots when TRUE.
- decimal_places
 Integer digits for annotations.
- open_new_device
