What is dialr?

The R phone-number package stopped only parsing numbers and started asking them where they are.

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

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.

The R phone-number package stopped only parsing numbers and started asking them where they are.

◆ Current state

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

◆ Where it's heading

Two forces shape the history. One is expansion into what libphonenumber knows beyond the number itself — carrier, geocode, timezone — which happened once, in 2019, and has not been extended since. The other is the ongoing cost of being a Java wrapper inside an R tidyverse: rJava initialisation moved so the :: form works, phone vectors reclassified when tibble 3.0.0 changed how it treats list-based classes, and repeated performance work to make crossing the Java boundary tolerable. The maintainer has floated moving the phone class onto vctrs but has not.

◆ Prediction

The vctrs migration is the one change the maintainer has explicitly signalled, and the hard-deprecated one-shot functions were slated for removal in the next major release; three years of silence make neither imminent.

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.
