collections vs sasr
A side-by-side editorial comparison of collections and sasr — release velocity, themes, recent moves, and the top alternatives to consider.
collections vs sasr: at a glance
What is collections?
A stable R data-structure package whose releases are now mostly compiler and checker upkeep.
collections provides queue, stack, deque, dict and ordered-dict types for R backed by C. The API has been settled since 0.3.x; recent releases are almost entirely maintenance against R's own tooling — an rchk memory-safety fix, then a modernization of the R/C interface. The one substantive change in the visible window is O(1) size() for queues and stacks.
What is sasr?
An R package that runs SAS code in a SAS session and hands the results back.
sasr is a bridge from insightsengineering: it opens SAS sessions from R, executes SAS code in them, pulls back logs and results, and moves datasets in both directions. All three visible tags carry byte-identical release notes reading "First CRAN version", so the changelog records the package's scope rather than any per-release delta. There is no visible activity after the May 2023 CRAN landing.

◆ Current state
collections provides queue, stack, deque, dict and ordered-dict types for R backed by C. The API has been settled since 0.3.x; recent releases are almost entirely maintenance against R's own tooling — an rchk memory-safety fix, then a modernization of the R/C interface. The one substantive change in the visible window is O(1) size() for queues and stacks.
◆ Where it's heading
This is a finished package under custodial maintenance. The releases track pressure from outside the package — CRAN's rchk checks, R's evolving C API — rather than user-facing demand, and the issue-to-release pattern shows changes arriving one contributed pull request at a time.
◆ Prediction
Further releases will most likely be more R C-API conformance work as R continues restricting non-API entry points; nothing in the entries points at new data structures.
sasr
0.0DEVOPS
An R package that runs SAS code in a SAS session and hands the results back.
◆ Current state
sasr is a bridge from insightsengineering: it opens SAS sessions from R, executes SAS code in them, pulls back logs and results, and moves datasets in both directions. All three visible tags carry byte-identical release notes reading "First CRAN version", so the changelog records the package's scope rather than any per-release delta. There is no visible activity after the May 2023 CRAN landing.
◆ Where it's heading
The three tags land in nineteen days and say the same thing, which means the arc here is a single push to get an initial version onto CRAN rather than a development sequence. What the notes do establish is a deliberate scope: session lifecycle, code execution, log retrieval and dataset transfer, and nothing beyond that. The package positions itself as plumbing between two runtimes rather than as an attempt to reimplement SAS procedures in R.
◆ Prediction
With identical notes across every tag and no entries since May 2023, the changelog gives no basis for predicting a next move. Any future release would most plausibly track the SAS session interface it wraps.
