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 gpkg?

An R interface to GeoPackage that keeps sanding down its own API

gpkg gives R users a direct handle on GeoPackage files — the SQLite-based OGC container for vector and raster layers — through lazy table access, OGR/SQLite dialect queries and terra integration. Recent releases center on raster write ergonomics: automatic NoData selection via auto_nodata and an exported gpkg_default_nodata() following GDAL and terra conventions. Release bodies are cumulative, folding two or three versions into one entry.

accessr vs gpkg: editorial side-by-side

INFRA · APIS
0.0

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.

An R interface to GeoPackage that keeps sanding down its own API

◆ Current state

gpkg gives R users a direct handle on GeoPackage files — the SQLite-based OGC container for vector and raster layers — through lazy table access, OGR/SQLite dialect queries and terra integration. Recent releases center on raster write ergonomics: automatic NoData selection via auto_nodata and an exported gpkg_default_nodata() following GDAL and terra conventions. Release bodies are cumulative, folding two or three versions into one entry.

◆ Where it's heading

The package is still finding its interface shape, and most releases pair a small capability with a deprecation or signature change — destfile giving way to y, gpkg_create_dummy_features deprecated, vapour swapped out for gdalraster. The consistent direction is deferring to GDAL and terra conventions rather than inventing gpkg-specific behaviour, and pushing connection management out of users' hands. Cadence is roughly one release a year with dependency automation now in CI.

◆ Prediction

Expect further alignment of write-path defaults with GDAL conventions and continued deprecation-with-replacement of early argument names, with an ogr2ogr-style path for out-of-memory vector data flagged as a possibility rather than a commitment.
