lazyeval vs procs
A side-by-side editorial comparison of lazyeval and procs — release velocity, themes, recent moves, and the top alternatives to consider.
lazyeval vs procs: 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 procs?
An R package rebuilding SAS procedures one PROC at a time, now filling in their options.
procs reimplements SAS statistical procedures — FREQ, MEANS, TTEST, REG, SORT, TRANSPOSE — as R functions returning both datasets and report-ready output, as part of the r-sassy suite. The catalogue of procedures is largely assembled; recent releases concentrate on the parameters each one accepts rather than on adding new procedures. Validation documentation is maintained alongside the code, consistent with the regulated environments the suite targets.

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.
procs
0.0ANALYTICS
An R package rebuilding SAS procedures one PROC at a time, now filling in their options.
◆ Current state
procs reimplements SAS statistical procedures — FREQ, MEANS, TTEST, REG, SORT, TRANSPOSE — as R functions returning both datasets and report-ready output, as part of the r-sassy suite. The catalogue of procedures is largely assembled; recent releases concentrate on the parameters each one accepts rather than on adding new procedures. Validation documentation is maintained alongside the code, consistent with the regulated environments the suite targets.
◆ Where it's heading
The work has shifted from breadth to fidelity: where earlier releases introduced whole procedures, recent ones add the options a SAS user expects to find on them, most visibly the where parameter spread across five functions at once and plotting support across three. Statistical output is being widened too, with AIC and adjusted Chi-Square appearing. The remaining gap is per-procedure option coverage rather than missing procedures.
◆ Prediction
Expect continued option-level parity work on the existing procedures, with new statistics added to their output tables, rather than a new proc_* function.

Frequently asked questions
What is the difference between lazyeval and procs?
They serve adjacent needs but don't currently overlap on shipped themes. lazyeval and procs are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is lazyeval better than procs?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. lazyeval and procs are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
