A side-by-side editorial comparison of accessibility and tern.mmrm — release velocity, themes, recent moves, and the top alternatives to consider.
accessibility vs tern.mmrm: 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 tern.mmrm?
An MMRM tabulation package that has published nothing since its 2024 CRAN releases.
tern.mmrm wraps mixed models for repeated measures into the tern tabulation and plotting layer used by teal clinical modules. The visible history ends with three CRAN releases in mid-to-late 2024; before that the feed carries only automated version bumps from 2022, three of which have just been backfilled into the record. The most recent substantive change adds axis limit arguments to the LS-means plot.

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.
tern.mmrm
0.0ANALYTICS
An MMRM tabulation package that has published nothing since its 2024 CRAN releases.
◆ Current state
tern.mmrm wraps mixed models for repeated measures into the tern tabulation and plotting layer used by teal clinical modules. The visible history ends with three CRAN releases in mid-to-late 2024; before that the feed carries only automated version bumps from 2022, three of which have just been backfilled into the record. The most recent substantive change adds axis limit arguments to the LS-means plot.
◆ Where it's heading
Content per release is thin and largely organisational: a maintainer change, replacing scda with random.cdisc.data in vignettes, and adapting to new {mmrm} versions. The package appears to be in maintenance, tracking its upstream dependency rather than developing independently. The 2022 entries now visible are release-automation commits, not releases in any meaningful sense.
◆ Prediction
Nothing here signals new functionality; the realistic next event is another compatibility release when {mmrm} or {rtables} changes underneath it.
