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 SimInf?
SimInf 10.0 turns an epidemic simulator into a tool that fits models to real time series
SimInf simulates stochastic disease spread over networks of nodes, with a model parser that compiles user-specified transitions to C. Version 10.0.0 was a deliberate major break: the SimInf_pfilter S4 class and the bootstrap filtering interface were redesigned, a replicates slot was added to SimInf_model, a multi-particle variant of the split-step solver arrived, and the package gained Particle Markov Chain Monte Carlo fitting against observed time series. The follow-up 10.1.0 is a single zero-length memcpy fix found by CRAN's M1 checks.

A redistricting toolkit that grows mostly by wiring in new public data sources
◆ 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.

SimInf 10.0 turns an epidemic simulator into a tool that fits models to real time series
◆ Current state
SimInf simulates stochastic disease spread over networks of nodes, with a model parser that compiles user-specified transitions to C. Version 10.0.0 was a deliberate major break: the SimInf_pfilter S4 class and the bootstrap filtering interface were redesigned, a replicates slot was added to SimInf_model, a multi-particle variant of the split-step solver arrived, and the package gained Particle Markov Chain Monte Carlo fitting against observed time series. The follow-up 10.1.0 is a single zero-length memcpy fix found by CRAN's M1 checks.
◆ Where it's heading
The package has been moving from simulation toward inference for several releases. The 9.x line built the input side — utilities for cleaning raw individual event data, variables and enumeration constants in the model parser — and 10.0.0 closed the loop by making the simulator fittable to data through PMCMC. The version number was incremented precisely because that required breaking the particle filter interface.
◆ Prediction
Fitting machinery this new usually needs a second pass on usability, so the next releases most likely focus on diagnostics and documentation around PMCMC rather than on the simulation core, which has been stable across the whole 9.x and 10.x history.
