accessibility vs verbalisr: 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 verbalisr?
Turns pedigree relationships into readable sentences, and is now tuning how those sentences read.
verbalisr describes the relationship between two people in a pedigree in plain language, and sits inside the pedsuite family alongside pedtools and ribd. The recent arc is about output control rather than new analysis: 0.6.0 added a simplify option for lineal and avuncular descriptions, 0.7.1 added abbreviate and collapse formatting arguments, and 0.7.2 made relationships with many paths noticeably faster.

◆ 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.
verbalisr
0.0ANALYTICS
Turns pedigree relationships into readable sentences, and is now tuning how those sentences read.
◆ Current state
verbalisr describes the relationship between two people in a pedigree in plain language, and sits inside the pedsuite family alongside pedtools and ribd. The recent arc is about output control rather than new analysis: 0.6.0 added a simplify option for lineal and avuncular descriptions, 0.7.1 added abbreviate and collapse formatting arguments, and 0.7.2 made relationships with many paths noticeably faster.
◆ Where it's heading
The package has moved from getting the descriptions correct to making them presentable and cheap to compute. Every recent release pins a newer pedtools, so its version cadence is tied to the wider pedsuite rather than to demand from its own users. Path-heavy pedigrees were evidently the practical bottleneck, and the latest release addresses that directly.
◆ Prediction
Expect the next release to follow a pedtools or ribd bump, most likely with further formatting options rather than new relationship categories, since the description logic itself has been stable across the entries shown.
