gigs vs mantis: at a glance
What is gigs?
gigs redesigned its whole conversion API for rOpenSci, then spent three releases getting the docs to build.
gigs implements international newborn and infant growth standards — INTERGROWTH-21st, WHO — converting anthropometric measurements to z-scores and centiles and classifying growth outcomes. The 0.5.0 release rewrote the public API around rOpenSci review feedback; the two releases after it change no code at all, existing purely to get the documentation site building.
What is mantis?
Thirteen months of rOpenSci review turned a pre-release into a 1.0 with a stable API
mantis builds interactive time-series reports — heatmaps, multipanel plots, alert tables — over routinely collected data, and its release history is essentially an rOpenSci peer-review log. The package went from a January 2025 pre-release that warned of breaking changes ahead, through submission and CRAN acceptance, to a 1.0.0 in October 2025 that locked the API. Since then it has shipped only two small fixes, the most recent chasing a dplyr 1.2.0 deprecation.

◆ Current state
gigs implements international newborn and infant growth standards — INTERGROWTH-21st, WHO — converting anthropometric measurements to z-scores and centiles and classifying growth outcomes. The 0.5.0 release rewrote the public API around rOpenSci review feedback; the two releases after it change no code at all, existing purely to get the documentation site building.
◆ Where it's heading
The package has moved from vector-in, vector-out conversion helpers to a data.frame-oriented interface with a single classify_growth() entry point that computes whatever outcomes the supplied columns allow. That is a shift from library to tool — the user describes their data rather than picking the right function. The trailing releases suggest the code is settled and the remaining work is packaging and discoverability.
◆ Prediction
With the API rewrite absorbed and hosting moved to rOpenSci, the next substantive release should add growth standards or outcomes rather than reshape the interface again.

Thirteen months of rOpenSci review turned a pre-release into a 1.0 with a stable API
◆ Current state
mantis builds interactive time-series reports — heatmaps, multipanel plots, alert tables — over routinely collected data, and its release history is essentially an rOpenSci peer-review log. The package went from a January 2025 pre-release that warned of breaking changes ahead, through submission and CRAN acceptance, to a 1.0.0 in October 2025 that locked the API. Since then it has shipped only two small fixes, the most recent chasing a dplyr 1.2.0 deprecation.
◆ Where it's heading
The breaking changes cluster entirely below 1.0.0 and stop there: `period` became `timepoint_unit`, `save_directory`/`save_filename` became `file`, `function_call` became `expression`. Post-1.0 the work is defensive — stricter POSIXt validation, timepoint limits that clamp to the data rather than inventing plot points, daylight-savings handling. The feed reads as a package that has finished defining itself and is now maintaining compatibility with the tidyverse underneath it.
◆ Prediction
With the API frozen and review complete, expect the next release to be another upstream-compatibility fix rather than new report types. There is no signal in these entries about planned feature work.
