Plot a gg_brier object

Description

Plot the time-resolved Brier score (default) or running CRPS for a survival forest, optionally overlaid with a 15-85 percent per-subject envelope.

Usage

## S3 method for class 'gg_brier'
plot(x, type = c("brier", "crps"), envelope = FALSE, ...)

Arguments

x	A gg_brier object.
type	Which series to plot: "brier" (default) or "crps".
envelope	Logical. When TRUE, overlays a ribbon spanning the 15th-85th percentile of per-subject Brier (or running CRPS) contributions at each time, around the overall line. When FALSE (default), draws the overall series only.
...	Extra arguments forwarded to geom_line().

Value

A ggplot object.
