geomander vs timeplyr: at a glance
What is geomander?
A redistricting toolkit that grows mostly by wiring in new public data sources
geomander provides geographic tools for redistricting analysis in R — matching and aggregating across block, VTD and district geometries, spatial diagnostics, and download helpers for the datasets the field relies on. Recent work splits between data access, with fetchers added for Jeffrey B. Lewis's historical congressional districts and RPV Near Me, and performance, with 2.5.0 delivering large speed gains in geo_match().
What is timeplyr?
timeplyr cut everything that wasn't time, then rebuilt intervals as fixed-width vectors.
timeplyr is a time-aware companion to dplyr and data.table, built around a fixed-width time_interval vector class. The 1.0.0 rewrite removed most non-time functions and pushed the C++ layer out into the separate cheapr package, leaving a narrower surface than the 0.8.x line. Releases since have been small: one feature batch in 1.1.1 and a pair of bug fixes in 1.1.2.

◆ Current state
geomander provides geographic tools for redistricting analysis in R — matching and aggregating across block, VTD and district geometries, spatial diagnostics, and download helpers for the datasets the field relies on. Recent work splits between data access, with fetchers added for Jeffrey B. Lewis's historical congressional districts and RPV Near Me, and performance, with 2.5.0 delivering large speed gains in geo_match().
◆ Where it's heading
The package is consolidating as infrastructure rather than expanding its analytical surface. Each release either adds a source of redistricting data that users would otherwise download by hand, or makes the core geographic matching operations faster and more correct — the normalized global Moran's I correction and the block-level geometry mismatch fix both fall in the second category. geo_match() being the target of the most recent release confirms where the hot path is.
◆ Prediction
With geo_match() now optimised, the remaining friction is in the download helpers, several of which have needed repair after upstream changes; expect the next release to consolidate or harden those fetchers rather than add analysis functions.
timeplyr
0.0ANALYTICS
timeplyr cut everything that wasn't time, then rebuilt intervals as fixed-width vectors.
◆ Current state
timeplyr is a time-aware companion to dplyr and data.table, built around a fixed-width time_interval vector class. The 1.0.0 rewrite removed most non-time functions and pushed the C++ layer out into the separate cheapr package, leaving a narrower surface than the 0.8.x line. Releases since have been small: one feature batch in 1.1.1 and a pair of bug fixes in 1.1.2.
◆ Where it's heading
The arc is consolidation, not expansion. Each release since 1.0.0 trims arguments, renames functions toward a single vocabulary (width, timespan, grid), or fixes an interaction with data.table's own rolling functions. The package increasingly acts as a thin time layer over cheapr and data.table rather than carrying its own implementation.
◆ Prediction
Expect continued small releases tracking cheapr and data.table changes rather than new function families; the entries show no in-progress feature work beyond the ggplot2-friendly breakpoint helpers introduced in 1.1.1.

Frequently asked questions
What is the difference between geomander and timeplyr?
They serve adjacent needs but don't currently overlap on shipped themes. geomander and timeplyr 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 geomander better than timeplyr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. geomander and timeplyr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
