plot_stability: Plot stability distribution

In unsurv: Unsupervised Clustering of Individualized Survival Curves

Plot stability distribution

Description

Convenience helper to visualize the distribution of Adjusted Rand Index values returned by unsurv_stability(...) when return_distribution = TRUE.

Usage

plot_stability(stab)

Arguments

stab	Either the numeric vector of ARI values or the list returned by unsurv_stability(..., return_distribution = TRUE).

Value

A ggplot histogram with a dashed line at the mean ARI.

Examples

if (requireNamespace("cluster", quietly = TRUE)) {
  set.seed(1)
  times <- seq(0, 4, length.out = 25)
  grp <- rep(1:2, each = 10)
  rates <- c(0.2, 0.55)
  S <- sapply(times, function(t) exp(-rates[grp] * t))
  fit <- unsurv(S, times, K = 2)
  stab <- unsurv_stability(S, times, fit, B = 6, frac = 0.7)
  plot_stability(stab)
}
