lazyeval vs logr: at a glance
What is lazyeval?
A package retired in 2017 just got rewritten against R's public C API.
lazyeval was the tidyverse's pre-rlang non-standard evaluation layer, formally set aside in 2017 when tidy evaluation replaced it. After eight and a half years without a release, 0.2.3 arrives as a compliance rewrite: the implementation now uses R's public C API, and the release note states it may differ from the historical one in subtle ways. Nothing about the package's role has changed.
What is logr?
A SAS-style logging package for R, shipping small and slowly by design.
logr produces SAS-style log files for R scripts, and is one component of the r-sassy suite aimed at analysts migrating clinical and pharmaceutical workflows off SAS. Release notes are terse — often a single line — and the cadence has thinned considerably, with one release in 2026 following a long gap. The functionality visible across this window is essentially complete: handlers, suspend and resume, explicit log_info/log_error/log_warning entries, and console output.

A package retired in 2017 just got rewritten against R's public C API.
◆ Current state
lazyeval was the tidyverse's pre-rlang non-standard evaluation layer, formally set aside in 2017 when tidy evaluation replaced it. After eight and a half years without a release, 0.2.3 arrives as a compliance rewrite: the implementation now uses R's public C API, and the release note states it may differ from the historical one in subtle ways. Nothing about the package's role has changed.
◆ Where it's heading
This is a dormancy revival driven entirely from outside, R core tightening what counts as the public C API forces packages using older internals to be rewritten or be archived. lazyeval is still a dependency deep in older package trees, so keeping it installable matters more than developing it. The caveat about subtle behavioural differences is the notable part: a package nobody is developing has changed behaviour in ways its release note declines to enumerate.
◆ Prediction
Expect no further development, only additional compliance releases if R core tightens the C API again.
logr
2.5ANALYTICS
A SAS-style logging package for R, shipping small and slowly by design.
◆ Current state
logr produces SAS-style log files for R scripts, and is one component of the r-sassy suite aimed at analysts migrating clinical and pharmaceutical workflows off SAS. Release notes are terse — often a single line — and the cadence has thinned considerably, with one release in 2026 following a long gap. The functionality visible across this window is essentially complete: handlers, suspend and resume, explicit log_info/log_error/log_warning entries, and console output.
◆ Where it's heading
The arc runs from correctness work on warning and error capture toward giving users control over where log output goes and how it is formatted. Recent releases are refinements of message content rather than new logging concepts, which is what a package settling into maintenance looks like. Nothing in these entries suggests an expansion of scope beyond the SAS-log-emulation brief.
◆ Prediction
Expect continued low-volume maintenance releases refining message detail and integration with the rest of the r-sassy suite, rather than new logging capability.
