accessr vs ordbetareg: 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 ordbetareg?
A brms wrapper for bounded outcomes that keeps handing users more control over the model's internals.
ordbetareg fits ordered beta regression — outcomes bounded at both ends, with mass at the bounds — on top of brms. Each release has opened up a layer that was previously fixed: v0.5.0 added posterior predictive checks and user-specified bounds, and v0.8 added a full prior override that makes cutpoint modeling possible, plus component-wise prediction of the bottom, middle and top of the scale.

◆ 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.
ordbetareg
0.0INFRA · APIS
A brms wrapper for bounded outcomes that keeps handing users more control over the model's internals.
◆ Current state
ordbetareg fits ordered beta regression — outcomes bounded at both ends, with mass at the bounds — on top of brms. Each release has opened up a layer that was previously fixed: v0.5.0 added posterior predictive checks and user-specified bounds, and v0.8 added a full prior override that makes cutpoint modeling possible, plus component-wise prediction of the bottom, middle and top of the scale.
◆ Where it's heading
The direction is from a convenience wrapper toward something users can take apart. The pattern across releases is the same move repeated at greater depth: what was hard-coded becomes an argument. Documentation is expanding in step, with the vignette now covering power analysis and cutpoint modeling, which suggests the audience is being taught to use the lower-level controls rather than the defaults.
◆ Prediction
Given that priors, bounds and predicted components are now all exposed, the next release most plausibly extends the diagnostic and plotting surface rather than the model itself — though releases here are more than a year apart, so timing is unpredictable.
