collections vs secretbase
A side-by-side editorial comparison of collections and secretbase — release velocity, themes, recent moves, and the top alternatives to consider.

collections vs secretbase: 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 secretbase?
secretbase quietly grew from a hashing package into a serialization toolkit
secretbase provides SHA-3, SHAKE, BLAKE3 and related hashing in R with a small C footprint and no dependencies. Over 2026 it has accumulated a second identity: CBOR, base58, JSON and URL-safe base64 encoders and decoders now sit alongside the hash functions. Releases are frequent, short and each does one thing — a format added, a conversion sped up, an undefined-behaviour warning cleared.

◆ 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.

secretbase quietly grew from a hashing package into a serialization toolkit
◆ Current state
secretbase provides SHA-3, SHAKE, BLAKE3 and related hashing in R with a small C footprint and no dependencies. Over 2026 it has accumulated a second identity: CBOR, base58, JSON and URL-safe base64 encoders and decoders now sit alongside the hash functions. Releases are frequent, short and each does one thing — a format added, a conversion sped up, an undefined-behaviour warning cleared.
◆ Where it's heading
The additions are not arbitrary. CBOR is a binary format for structured data, JSON its text counterpart, base58 the checksummed encoding used for identifiers — together they cover what a process needs to put an R object on a wire and get it back, which is a different job from digesting bytes. The maintainer also maintains R's high-performance messaging stack, and a dependency-free codec that handles integers, floats, strings, raw vectors and lists is exactly what that stack would consume.
◆ Prediction
Every format added so far has come with an RFC number and a minimal implementation rather than a wrapped library, so further additions are likely to follow the same pattern; the encoders are also being optimized after they land, suggesting performance passes on CBOR and JSON before anything new.
