What is formr?

formr's R client reached CRAN and moved its recommended path to the v1 REST API.

formr is the R-side client for formr.org, the open study framework used to run longitudinal and experience-sampling questionnaires. In May it reached CRAN for the first time, released in step with formr.org server v1.0.0, and the formr_api_* family built on the server's RESTful surface became the supported entry point. The three releases since have been repair work on the paths that move rendered output and API results.

What is JointFPM?

Recurrent-event modelling settles, with mean_no() promoted to stable.

JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.

formr's R client reached CRAN and moved its recommended path to the v1 REST API.

◆ Current state

formr is the R-side client for formr.org, the open study framework used to run longitudinal and experience-sampling questionnaires. In May it reached CRAN for the first time, released in step with formr.org server v1.0.0, and the formr_api_* family built on the server's RESTful surface became the supported entry point. The three releases since have been repair work on the paths that move rendered output and API results.

◆ Where it's heading

The direction is consolidation around the v1 API while the legacy Classic path is left running but demoted in the vignette. The complication is that CRAN's requirements and the OpenCPU server's requirements pull against each other: CRAN review pushed rendering into tempdir() with random filenames, which broke rforms.org because the server fetches a fixed knit.html, and 1.1.2 had to put it back. The 1.2.0 note describes the same write-directory problem being solved in an OpenCPU-aware way rather than reverted, alongside making dependencies installable under WASM.

◆ Prediction

Two of the last three releases were regressions in the render path, so the OpenCPU-aware write directory in 1.2.0 is the change most likely to need follow-up. The Classic formr_results() path remains in the package with no removal date announced, and nothing in these entries indicates when that ends.

Recurrent-event modelling settles, with mean_no() promoted to stable.

◆ Current state

JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.

◆ Where it's heading

The arc runs from a working estimator toward a usable one: input validation and error messages first, then control over the numerical integration, then a summary method and pass-through arguments to the underlying rstpm2 fit. The latest release adds no code so much as a stability commitment to a function users were already calling.

◆ Prediction

With mean_no() stable, the next work most likely targets the prediction and standardization paths rather than the model fit itself.
