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 treespace?

treespace ships once every year or two, and only when CRAN or a user forces it.

treespace explores and compares sets of phylogenetic and transmission trees, including the tree-distance measures used in outbreak reconstruction. Its release history is entirely reactive: five updates across five years, each triggered by a CRAN policy change, an upstream package removal, or a bug someone reported. The most recent is an Rd cross-reference format patch plus a maintainer email change.

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.

treespace ships once every year or two, and only when CRAN or a user forces it.

◆ Current state

treespace explores and compares sets of phylogenetic and transmission trees, including the tree-distance measures used in outbreak reconstruction. Its release history is entirely reactive: five updates across five years, each triggered by a CRAN policy change, an upstream package removal, or a bug someone reported. The most recent is an Rd cross-reference format patch plus a maintainer email change.

◆ Where it's heading

The package is stable and lightly staffed rather than abandoned — bugs that affect correctness do get fixed, and CRAN deadlines are met. But the 2023 update is the telling one: rather than vendor or replace adephylo when it faced removal, the maintainers disabled two tree-vector methods and marked the loss as hopefully temporary. Two years on, nothing in the feed indicates they came back.

◆ Prediction

The next entry will most likely be another CRAN-compliance patch, on the pattern of four of the last five releases. Whether the Abouheif and sumDD methods ever return is not something these entries give any signal on.
