forcis vs slider
A side-by-side editorial comparison of forcis and slider — release velocity, themes, recent moves, and the top alternatives to consider.
forcis vs slider: at a glance
What is forcis?
A foraminifera data-access package whose entire release history is the rOpenSci review process.
forcis provides R access to the FORCIS database of planktonic foraminifera occurrences. All three releases in the window are review milestones rather than feature work: first stable release, the release answering rOpenSci reviewer comments, and a post-CRAN-review polish. Release notes point at NEWS.md rather than enumerating changes.
What is slider?
Feature-complete since 2021, and every release since has been paying CRAN's C API bill
slider provides sliding-window and index-aware window functions for R, with a C implementation underneath and a specialised fast path for common aggregations. The user-facing surface has been stable since 0.3.0 in late 2022. Everything after that is compliance and platform work: STRING_PTR removed in 0.3.2, OBJECT() removed in 0.3.3, a vctrs callable's C signature corrected, and the minimum R version raised twice.

forcis
0.0ANALYTICS
A foraminifera data-access package whose entire release history is the rOpenSci review process.
◆ Current state
forcis provides R access to the FORCIS database of planktonic foraminifera occurrences. All three releases in the window are review milestones rather than feature work: first stable release, the release answering rOpenSci reviewer comments, and a post-CRAN-review polish. Release notes point at NEWS.md rather than enumerating changes.
◆ Where it's heading
The package is moving from research artifact to reviewed, distributable infrastructure — submitted to rOpenSci at 0.1.0, integrated review feedback at 1.0.0, cleared CRAN at 1.0.1. That arc is complete, so the next phase should be the first release driven by users rather than reviewers.
◆ Prediction
With review and CRAN acceptance both behind it, the next release is most likely to track upstream FORCIS database changes or add query conveniences; the entries themselves say nothing about planned features.

Feature-complete since 2021, and every release since has been paying CRAN's C API bill
◆ Current state
slider provides sliding-window and index-aware window functions for R, with a C implementation underneath and a specialised fast path for common aggregations. The user-facing surface has been stable since 0.3.0 in late 2022. Everything after that is compliance and platform work: STRING_PTR removed in 0.3.2, OBJECT() removed in 0.3.3, a vctrs callable's C signature corrected, and the minimum R version raised twice.
◆ Where it's heading
Two forces set the release schedule, and neither is feature demand. The first is CRAN closing off non-API C entry points, which packages reaching into R internals for speed have to unwind one accessor at a time — slider is on its second such release with no visible loss of function. The second is vctrs, whose breaking changes slider absorbs ahead of time; 0.2.2 exists solely to prepare for one. The last release that added anything callers can see was 0.3.0's slider_plus() and slider_minus() extension hooks.
◆ Prediction
Expect the pattern to continue: another non-API accessor removal or a vctrs compatibility release, rather than new window functions. The C-level surface is the only part of this package still moving.
