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 Knock?

Knock is hardening for enterprise buyers while its agent takes over the analysis work.

Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

accessr vs Knock: editorial side-by-side

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.

Knock is hardening for enterprise buyers while its agent takes over the analysis work.

◆ Current state

Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

◆ Where it's heading

Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.

◆ Prediction

Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
