What is atrrr?

The R client for Bluesky adds a firehose and stops assuming Bluesky is the server

atrrr wraps the AT Protocol for R, covering posting, search, profiles, lists, direct messages and starter packs. The latest release adds an experimental firehose implementation and allows connecting to personal data servers other than Bluesky's — Eurosky is the example given. Earlier releases built out the posting surface: videos, multiple images, link preview cards, hashtags, and ggplot2 objects posted directly.

What is simStateSpace?

State-space data simulation for R, filled in one function at a time

simStateSpace generates data from state-space models — discrete-time SSM and VAR, continuous-time linear SDE and Ornstein-Uhlenbeck — for use in simulation studies of longitudinal and intensive repeated-measures designs. Recent releases add moment and intercept helpers rather than new model families: SimMVN(), the LinSDE intercept functions, and consolidation of the four separate parameter-simulation functions into one. Release notes are terse, marked Patch, and typically name one or two functions.

The R client for Bluesky adds a firehose and stops assuming Bluesky is the server

◆ Current state

atrrr wraps the AT Protocol for R, covering posting, search, profiles, lists, direct messages and starter packs. The latest release adds an experimental firehose implementation and allows connecting to personal data servers other than Bluesky's — Eurosky is the example given. Earlier releases built out the posting surface: videos, multiple images, link preview cards, hashtags, and ggplot2 objects posted directly.

◆ Where it's heading

Two years of work made atrrr a capable REST client for one network. This release starts undoing that second part. The firehose is a different access mode — a stream rather than a request — which is what researchers doing collection at scale need, and PDS-agnosticism means the package addresses the protocol rather than the company. The rest of the changelog is steadily maintenance-shaped: repeated httr2 compatibility work, endpoint changes tracked as they happen.

◆ Prediction

The firehose is labelled experimental, so the next release most likely stabilises it rather than opening another front — though the notes give no detail on what remains unfinished.

State-space data simulation for R, filled in one function at a time

◆ Current state

simStateSpace generates data from state-space models — discrete-time SSM and VAR, continuous-time linear SDE and Ornstein-Uhlenbeck — for use in simulation studies of longitudinal and intensive repeated-measures designs. Recent releases add moment and intercept helpers rather than new model families: SimMVN(), the LinSDE intercept functions, and consolidation of the four separate parameter-simulation functions into one. Release notes are terse, marked Patch, and typically name one or two functions.

◆ Where it's heading

The package is being filled in methodically toward completeness across its four model families — whatever exists for the SSM side eventually appears for LinSDE and back again, as SSMInterceptEta/SSMInterceptY in 1.2.15 were followed by their LinSDE counterparts in 1.2.16. The other visible move was outward: bootstrap components were split into a separate bootStateSpace package, keeping this one to simulation alone. It sits in the same author's cluster of state-space and mediation packages, whose published methods papers the releases cite.

◆ Prediction

Expect the pattern to continue — small patch releases adding the missing counterpart function for a model family already served, with any larger capability likely spun out into its own package as bootstrapping was.
