mantis vs Tplyr: at a glance
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.
What is Tplyr?
Tplyr made clinical summary tables explain where every number came from.
Tplyr builds clinical summary tables through a layered grammar — count, descriptive statistics, and shift layers assembled onto a table object. The 1.0.0 release added a traceability metadata framework that lets a user ask which source rows produced any given cell, and later releases extended it to cases the first pass missed. The package is maintained by Atorus within the pharmaverse ecosystem.

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.
Tplyr
0.0ANALYTICS
Tplyr made clinical summary tables explain where every number came from.
◆ Current state
Tplyr builds clinical summary tables through a layered grammar — count, descriptive statistics, and shift layers assembled onto a table object. The 1.0.0 release added a traceability metadata framework that lets a user ask which source rows produced any given cell, and later releases extended it to cases the first pass missed. The package is maintained by Atorus within the pharmaverse ecosystem.
◆ Where it's heading
Post-1.0 work has been about completing the metadata story and filling gaps in layer composition rather than adding table types — metadata for missing subjects, add_anti_join(), missing-subject rows, data limiting, and fixes to nested count layers where an inner value appears under several outer groups. Releases cluster tightly after a major version, then go quiet, and the window ends with a patch issued days after the release it corrects.
◆ Prediction
Further releases will most likely continue closing traceability and nested-layer edge cases rather than introducing new layer types, following the pattern of both post-1.0 feature releases.
