accessibility vs poppr: at a glance
What is accessibility?
An urban accessibility toolkit that grew into a distributional-equity toolkit.
accessibility, from IPEA's geo team, computes how reachable opportunities are given a travel matrix and land use data. Since the 1.0.0 rebuild it has widened well past reachability metrics: 1.1.0 added inequality and poverty estimation alongside spatial availability and balancing cost, 1.2.0 added the concentration index and Theil T, and 1.3.0 let spatial_availability() return results per origin-destination pair with the underlying balancing factors exposed.
What is poppr?
A population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.

An urban accessibility toolkit that grew into a distributional-equity toolkit.
◆ Current state
accessibility, from IPEA's geo team, computes how reachable opportunities are given a travel matrix and land use data. Since the 1.0.0 rebuild it has widened well past reachability metrics: 1.1.0 added inequality and poverty estimation alongside spatial availability and balancing cost, 1.2.0 added the concentration index and Theil T, and 1.3.0 let spatial_availability() return results per origin-destination pair with the underlying balancing factors exposed.
◆ Where it's heading
The package is moving from measuring access to measuring who is left out, and doing it by adding metrics rather than reworking the core. A second, quieter theme is generality — nearly every parameter that once took a single value now accepts vectors or lists, so users can sweep across cutoffs and decay specifications in one call. The decay family keeps growing, most recently with a logistic form.
◆ Prediction
Further inequality or decay functions are the most likely next addition, given that both families have grown steadily and neither shows signs of being considered complete; the entries give no indication of another breaking restructure.
poppr
0.0ANALYTICS
A population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
◆ Current state
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.
◆ Where it's heading
This is a mature package being kept installable rather than developed. The deprecation promised in 2.9.0 — removing blacklist in 2.10 — has not arrived across three years and four releases, which is the clearest sign that no feature line is currently active. What movement exists comes from outside contributors and from the toolchain moving underneath the package.
◆ Prediction
The next release is most likely another CRAN or compiler-compatibility fix; the promised 2.10 removal of blacklist would be the first sign of active development resuming, but nothing in these entries indicates it is being prepared.
