R provides fantastic tools for changepoint analysis, but plots generated by the tools do not have the 'ggplot2' style. This tool, however, combines 'changepoint', 'changepoint.np' and 'ecp' together, and uses 'ggplot2' to visualize changepoints. Version 0.2.0 adds a unified 'ggcpt' S3 result class, 'broom'-style tidy/glance/augment methods, 'autoplot()', new geoms ('geom_changepoint()', 'geom_cpt_segment()', 'geom_cpt_ci()', 'stat_changepoint()'), a unified 'cpt_detect()' dispatcher, first-wave wrappers for WBS/WBS2, NOT, MOSUM, FPOP, a method comparison module, accuracy metrics, data simulation, canonical test signals, and hardening of the existing functions (no-change bug fix, 'size' to 'linewidth' migration, 'match.arg()' validation).
