to describe the unified ggcpt framework and the current
13-method engine list (it previously still claimed “only three
changepoint packages”).cpt_methods() introspection helper returning a
tibble of every known method, its engine, availability status, and
whether the engine is installed.ggcpt class:
summary(), as_tibble(),
as.data.frame(), format(), and
plot().cpt_penalty() gained a documented per-engine
penalty-semantics section.cpt_detect() no longer advertises 13 methods that
errored at runtime; match.arg() now enumerates only the
wired methods (B7).cpt_detect() validates method ×
change_in combinations and errors with a clear message
instead of silently mislabelling the result (B3).signal_blocks() now produces the correct Blocks signal;
the segment levels previously collapsed to a single step because the
assignment loop ran in reverse (B1).cpt_metrics() uses one-to-one matching, so
recall and f1 can no longer exceed 1 (B2), and
no longer warns on empty pred/truth (B6).ecp_wrapper() returns a correct per-coordinate
cp_value for matrix and data.frame input instead of a
column-major flattened scalar (B4); cpt_detect() no longer
flattens multivariate input before passing it to ecp.stat_changepoint() maps detected indices back to the
x aesthetic so rules land at the correct location on
non-1:n axes (B5).glance.ggcpt() now reports a measured
runtime and populates total_cost from the
underlying fit when available (B8).augment.ggcpt() renames data columns
position-independently, so it no longer breaks when the data carries
more than two columns (B11).cpt_simulate() @return now documents the
seg_id column it actually returns (B9), and the dead
show_segments parameter was removed from the internal plot
helper (B10).ggcpt S3 result class with tidy(),
