igoR vs rasterpic: at a glance
What is igoR?
igoR reached 1.0.0 with no user-visible change, then spent three releases on AI-assisted cleanup
igoR provides access to Intergovernmental Organizations (IGO) databases from the Correlates of War project. The dataset and public API have been stable for years; recent releases are almost entirely maintenance. 1.0.0 in January 2026 raised the minimum R version to 3.6.0 and stated explicitly that users would see no change.
What is rasterpic?
rasterpic became an S3 generic and picked up stars support; the rest is upkeep
rasterpic georeferences ordinary images onto spatial objects, producing terra SpatRasters that can be plotted as basemaps or overlays. The package is small and its job is narrow. The meaningful recent change is 0.5.0, which turned rasterpic_img() into an S3 generic with methods per input class and added support for stars objects alongside sf and terra.

◆ Current state
igoR provides access to Intergovernmental Organizations (IGO) databases from the Correlates of War project. The dataset and public API have been stable for years; recent releases are almost entirely maintenance. 1.0.0 in January 2026 raised the minimum R version to 3.6.0 and stated explicitly that users would see no change.
◆ Where it's heading
Development has shifted to documentation and internal consistency, and the mechanism is notable: 1.0.2 and 1.0.3 both describe AI-assisted editing and refactoring, part of a sweep the same maintainer ran across several packages in mid-2026. The one substantive fix in the window is igo_dyadic() computing dyadid from both state codes as documented. Everything else is dependency bumps and message wording.
◆ Prediction
With the internals refactored and documentation reviewed, further releases are likely to track upstream Correlates of War data updates rather than change the API. The entries give no indication of a pending data revision.

rasterpic became an S3 generic and picked up stars support; the rest is upkeep
◆ Current state
rasterpic georeferences ordinary images onto spatial objects, producing terra SpatRasters that can be plotted as basemaps or overlays. The package is small and its job is narrow. The meaningful recent change is 0.5.0, which turned rasterpic_img() into an S3 generic with methods per input class and added support for stars objects alongside sf and terra.
◆ Where it's heading
The direction is broader input-class coverage inside the same single-function design, and tighter integration with the plotting ecosystem downstream. 0.3.0 renamed output layers to r/g/b/alpha specifically to stay compatible with tmap 4.0; 0.5.1 restored the RGB specification on masked and inverted output after it regressed, and moved errors and warnings to cli formatting. Releases are frequent but small.
◆ Prediction
With the generic in place, adding further input classes is now cheap, so that is the likely direction. The 0.5.1 regression on mask/inverse output suggests the RGB-specification path is the fragile part worth watching.

Frequently asked questions
What is the difference between igoR and rasterpic?
Both compete on the same themes — r — within Analytics. igoR and rasterpic are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is igoR better than rasterpic?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. igoR and rasterpic are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
