accessr vs logger: at a glance
What is accessr?
One R Markdown source, four accessible formats — and a fortnight spent patching around someone else's bug.
accessr turns a single R Markdown file into HTML slides, HTML, Word and PDF output, with an emphasis on producing documents a screen reader can navigate. Accessible PDFs come via OfficeToPDF and are Windows-only, which is the package's main structural constraint. Recent releases have been spent absorbing and then unwinding a fault in the officedown dependency.
What is logger?
R's logging package handed to new maintainers and rebuilt from the inside out
logger structures R logging around four composable pieces — a level threshold, a formatter, a layout and an appender — a design fixed at the 2018 CRAN release and unchanged since. The recent work is all underneath it. 0.4.0 made metadata computation lazy so expensive fields cost nothing unless a layout uses them, swapped the custom background-process appender for mirai, and added native GitHub Actions output. 0.4.1 followed with elapsed-time logging, call site location exposed to layouts, a cli-based formatter, and knitr chunk timing. 0.4.2 is a small maintenance release adding an ntfy appender.

One R Markdown source, four accessible formats — and a fortnight spent patching around someone else's bug.
◆ Current state
accessr turns a single R Markdown file into HTML slides, HTML, Word and PDF output, with an emphasis on producing documents a screen reader can navigate. Accessible PDFs come via OfficeToPDF and are Windows-only, which is the package's main structural constraint. Recent releases have been spent absorbing and then unwinding a fault in the officedown dependency.
◆ Where it's heading
The package's own development is focused on the details that make output genuinely accessible rather than merely produced — PDF bookmarks generated from Word headings, image dimension handling, header behaviour in slide output. That work is intermittent, and the more visible pattern in 2025 is dependency fragility: a CRAN check failure traced to a strsplit() call inside officedown forced a temporary patch, which was reverted two weeks later once upstream fixed it. Depending on a chain of document-conversion tools means the package inherits their breakages.
◆ Prediction
The next release will likely be another response to an upstream document-tooling change, though the pdf_args work suggests further OfficeToPDF options could be exposed if accessibility gaps surface.

R's logging package handed to new maintainers and rebuilt from the inside out
◆ Current state
logger structures R logging around four composable pieces — a level threshold, a formatter, a layout and an appender — a design fixed at the 2018 CRAN release and unchanged since. The recent work is all underneath it. 0.4.0 made metadata computation lazy so expensive fields cost nothing unless a layout uses them, swapped the custom background-process appender for mirai, and added native GitHub Actions output. 0.4.1 followed with elapsed-time logging, call site location exposed to layouts, a cli-based formatter, and knitr chunk timing. 0.4.2 is a small maintenance release adding an ntfy appender.
◆ Where it's heading
Two things stand out. The original four-part architecture has absorbed six years of additions without being renegotiated — every new capability arrives as another formatter, layout or appender rather than a change to the contract. And the contributor pattern has shifted: 0.3.0 collected two years of scattered community patches, while 0.4.0 and 0.4.1 are concentrated work from a small number of prolific R-infrastructure maintainers, which reads as a handover of stewardship rather than a maintenance lull ending.
◆ Prediction
The pluggable design means new destinations and formatters are the path of least resistance, so expect further appenders in the mold of ntfy and Slack rather than changes to the core logging contract.
