contentiousR - Contentious Politics and Civil Conflict Research

Constructs reproducible country-year panels for research on contentious politics and civil conflict, as described in Guseinov (2026) <doi:10.2139/ssrn.7506799>. Functions build state panels keyed by Correlates of War or Gleditsch-Ward country codes and join curated socioeconomic, leadership, democracy, conflict, protest, and revolutionary-episode data on that common key, with diagnostics and plots for comparing source coverage. Bundled sources include Gapminder; the Nonviolent and Violent Campaigns and Outcomes (NAVCO) 2.1 data, Chenoweth and Shay (2019) <doi:10.7910/DVN/MHOXDV>; the Social Conflict Analysis Database, Salehyan et al. (2012) <doi:10.1080/03050629.2012.697426>; the Uppsala Conflict Data Program and Peace Research Institute Oslo (UCDP/PRIO) Armed Conflict Dataset, Gleditsch et al. (2002) <doi:10.1177/0022343302039005007>; and the Major Episodes of Contention data, Chenoweth and Kang (2026) <doi:10.1093/jopres/xjaf008>. Varieties of Democracy (V-Dem) indicators require the optional 'vdemdata' package, which is not on CRAN and can be installed from <https://github.com/vdeminstitute/vdemdata>.
