BiocManager vs fmtr
A side-by-side editorial comparison of BiocManager and fmtr — release velocity, themes, recent moves, and the top alternatives to consider.

BiocManager vs fmtr: at a glance
What is BiocManager?
Bioconductor's installer, frozen at 1.30.x and tuned almost entirely through environment variables
BiocManager is the entry point for installing Bioconductor packages and keeping an installation consistent with a Bioconductor release. It resolves which Bioconductor version pairs with the running R version, points at the right repositories, and handles the version-map logic behind that. The package version has sat at 1.30.x for years, with patch numbers carrying every change.
What is fmtr?
Rebuilding SAS's formatting layer in R, one format specification at a time
fmtr applies formats to R data the way SAS applies them: named format catalogues, format lists, and an fapply() that maps a specification onto a vector. It is part of a family of packages that reconstruct SAS reporting idioms in R, and it shares infrastructure with them — labels.data.frame() was moved out to the common package, which fmtr now depends on. The recent releases have been closing specific gaps against SAS's own format vocabulary.

BiocManager
0.0ANALYTICS
Bioconductor's installer, frozen at 1.30.x and tuned almost entirely through environment variables
◆ Current state
BiocManager is the entry point for installing Bioconductor packages and keeping an installation consistent with a Bioconductor release. It resolves which Bioconductor version pairs with the running R version, points at the right repositories, and handles the version-map logic behind that. The package version has sat at 1.30.x for years, with patch numbers carrying every change.
◆ Where it's heading
The consistent direction is making the installer's behaviour controllable without interactive prompts. Successive releases have added environment variables for site repositories, repository checks, the Bioconductor name used in binary URL resolution, and a deliberate override for running against an unsupported R version. That is a package being shaped by continuous integration and container use, where nothing can be answered at a prompt. Alongside it runs a slow cleanup of legacy surface, with the biocLite era finally removed in 2025.
◆ Prediction
The escape-hatch pattern is well established, so further environment-variable controls and continued pruning of legacy install paths are the most likely next moves.

Rebuilding SAS's formatting layer in R, one format specification at a time
◆ Current state
fmtr applies formats to R data the way SAS applies them: named format catalogues, format lists, and an fapply() that maps a specification onto a vector. It is part of a family of packages that reconstruct SAS reporting idioms in R, and it shares infrastructure with them — labels.data.frame() was moved out to the common package, which fmtr now depends on. The recent releases have been closing specific gaps against SAS's own format vocabulary.
◆ Where it's heading
The direction is parity, pursued in small increments. Quarter format codes were added because base R has none; the SAS best. format was reimplemented, then hardened against the variations people actually write; statistical summary helpers like fmt_mean_sd() and fmt_mean_stderr() cover the cell contents clinical tables need. The structural work is largely behind it, including the breaking 2022 move that handed labelling to a sibling package, so what remains is vocabulary coverage.
◆ Prediction
The pattern of adding a SAS format, then a release to handle its variants, suggests the next releases continue filling in format codes and summary helpers rather than changing how formats are applied.
