cranebased

Cranebased is an adjective used to describe software, workflows, or environments that are built around or depend on the Comprehensive R Archive Network (CRAN) as a primary source of R packages. In practice, cranebased systems install and manage packages from CRAN, enforce compatibility with specified R versions, and align with CRAN's packaging conventions and policies.

Origin and usage: The term derives from CRAN, the official repository for R packages, and is used in contexts where CRAN is central to installation, testing, and distribution. Cranebased approaches emphasize using CRAN as a trusted source of dependencies and a stable point of reference for project setup.

Characteristics: Cranebased software typically uses CRAN as the source for dependencies, relies on standard R functions such as install.packages, and may integrate with tooling to achieve reproducible environments. Tools and practices such as renv, packrat, or containerized workflows are often employed to capture the precise CRAN package set and versions used in a given project. Because CRAN maintains a centralized index of packages with versioning and checks, cranebased workflows emphasize reproducibility and traceability.

Limitations: Dependence on CRAN means reliance on network access and CRAN availability, adherence to CRAN policies, and potential delays when packages are updated or removed. Some projects may require system libraries or external tooling beyond CRAN, which can complicate maintenance.
