Evaluation visualization

Overlays predictions and ground truth on the series with tolerance windows, colouring true positives, false positives, and misses. Uses the same one-to-one matching as cpt_metrics(), so the plot and the metrics agree.

Usage

ggcpt_eval(pred, truth, data_vec, margin = 5)

Arguments

pred

Predicted changepoint indices.

truth

Ground truth changepoint indices.

data_vec

The original data vector (for context).

margin

Tolerance margin (default 5).

Value

A ggplot object.
