ggchangepoint - Combines Changepoint Analysis with 'ggplot2'

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. It provides a unified 'ggcpt' S3 result class, 'broom'-style tidy/glance/augment methods, 'autoplot()', composable geoms ('geom_changepoint()', 'geom_cpt_segment()', 'geom_cpt_ci()', 'stat_changepoint()'), a unified 'cpt_detect()' dispatcher with method introspection via 'cpt_methods()', wrappers for several optional engines (WBS, WBS2, NOT, MOSUM, FPOP, Isolate-Detect, TGUH), a method comparison module, accuracy metrics, data simulation, and canonical test signals.

countryatlas - Join World Bank Data, Country Codes and Maps on the ISO Spine

A complete toolkit for getting country data onto honest maps. Country names rarely line up across data sources ("US", "U.S.", "United States", "United States of America" are one country, but a naive join treats them as four), so 'countryatlas' makes ISO codes the universal join key. It generalises a one-call, map-ready table that stitches together 'ggplot2' map geometry, 'WDI' World Bank indicators and the 'countrycode' Rosetta stone; exposes the join machinery for the user's own data; ships curated reference data (metadata, group memberships, an indicator catalogue, flags and currencies); adds analysis helpers (per-capita, regional roll-ups, ranking); and turns one hand-drawn choropleth into a full vocabulary of projected, area-honest maps (binned and quantile choropleths, proportional-symbol, bivariate, cartogram, tile-grid, flow, animated, globe and interactive), and can hand its curated, ISO-reconciled tables to 'ggsql' for database-side spatial rendering. Heavy spatial dependencies stay optional, and a bundled offline snapshot lets every example, test and vignette run without the network.

ggDoubleHeat - A Heatmap-Like Visualization Tool

A data visualization design that provides comparison between two (Double) data sources (usually on a par with each other) on one reformed heatmap, while inheriting 'ggplot2' features.

tidyEmoji - Discover, Count and Score Emoji in Text

A tidy toolkit for working with the emoji in any text column, such as social-media posts, product reviews, chat logs or survey responses. Unicode is awkward to handle and not every code point is an emoji, which makes emoji statistics fiddly to obtain. 'tidyEmoji' extracts, counts, categorises and sentiment-scores emoji with grapheme-aware detection (so skin-tone and multi-person sequences stay intact), returning tidy data frames that slot straight into a 'tidyverse' workflow. The bundled emoji sentiment lexicon is from the Emoji Sentiment Ranking of Kralj Novak et al. (2015) <doi:10.1371/journal.pone.0144296>, released under CC BY-SA 4.0.

ggtaichi - Taichi-Diagram Visualization for Two Data Sources

A data visualization design that compares two (usually on a par with each other) data sources on one grid of taichi (yin-yang) diagrams, where the two interlocking fish of every symbol are filled by the two sources, while inheriting 'ggplot2' features.
