graphicalMCP vs vcr
A side-by-side editorial comparison of graphicalMCP and vcr — release velocity, themes, recent moves, and the top alternatives to consider.
graphicalMCP vs vcr: at a glance
What is graphicalMCP?
graphicalMCP is a narrow statistical tool being hardened rather than grown.
graphicalMCP implements graphical multiple comparison procedures — the method used to control family-wise error across several endpoints in a clinical trial. The package moved under the openpharma organisation in 0.2.6, picked up Hochberg tests and internal validation in 0.2.8, and its most recent release fixes a case where graph testing by closure disagreed with the rejection-based path. Releases are roughly annual and short.
What is vcr?
Added the HTTP client everyone moved to, then deleted a decade of its own public surface.
vcr records HTTP interactions to disk so R package tests can replay them without network access. Two releases define its current state. Version 1.6.0 added httr2 support alongside the existing httr and crul backends, following the R ecosystem's migration to httr2. Version 2.0 then removed a large amount of accumulated public surface — the logging functions, vcr_last_error(), the exported R6 classes including RequestHandler, Request, VcrResponse and HTTPInteractionList, and several configuration options that had stopped working or could not be implemented correctly.

graphicalMCP is a narrow statistical tool being hardened rather than grown.
◆ Current state
graphicalMCP implements graphical multiple comparison procedures — the method used to control family-wise error across several endpoints in a clinical trial. The package moved under the openpharma organisation in 0.2.6, picked up Hochberg tests and internal validation in 0.2.8, and its most recent release fixes a case where graph testing by closure disagreed with the rejection-based path. Releases are roughly annual and short.
◆ Where it's heading
The changelog reads as a package settling into reference-implementation status: procedure coverage widened once, then the work turned to proving the two computational routes through the same graph agree with each other. That agreement is the whole promise of this kind of tool, since the closure-based calculation is the definition and the rejection-based one is the fast path everyone actually runs. The openpharma move points the same direction — shared maintenance rather than a single author's project.
◆ Prediction
The entries show no feature roadmap, only correctness and validation work, so the next release is most likely another consistency or precision fix rather than a new procedure.
vcr
0.0ANALYTICS
Added the HTTP client everyone moved to, then deleted a decade of its own public surface.
◆ Current state
vcr records HTTP interactions to disk so R package tests can replay them without network access. Two releases define its current state. Version 1.6.0 added httr2 support alongside the existing httr and crul backends, following the R ecosystem's migration to httr2. Version 2.0 then removed a large amount of accumulated public surface — the logging functions, vcr_last_error(), the exported R6 classes including RequestHandler, Request, VcrResponse and HTTPInteractionList, and several configuration options that had stopped working or could not be implemented correctly.
◆ Where it's heading
The package is consolidating after years of additive growth. The 2.0 removals are almost all things that were exported without needing to be, or options that promised behaviour the implementation could not guarantee — check_cassette_names() was deprecated precisely because it cannot be made correct. Cassette maintenance is being simplified too, with re_record_interval now the single mechanism for expiring recordings.
◆ Prediction
Expect the post-2.0 releases to be about migration support and fallout from the removed API, since the breaking list is long enough that reverse dependencies will surface problems. Async support for httr2 stays blocked until req_perform_parallel gains a mocking hook, which the entries note is upstream work.

ymlthis
ymlthis retired itself, naming Quarto as the reason it no longer needs to exist.
forestly
forestly built an interactive safety review tool, then taught it to produce submission-ready RTF.
pharmaverseadam
pharmaverseadam is the pharmaverse's test-data mirror, and it now covers neurology.
pkglite
pkglite's whole job is knowing which files in an R package are text — and it keeps getting better at guessing.
gMCPLite
gMCPLite exists to be gMCP without Java, and its releases guard that boundary rather than extend it.
