Jun 1, 2025June 2025 monthly summary: Implemented Table Generation Enhancement with parent_name argument for tabulate_rsp_subgroups and tabulate_survival_subgroups to disambiguate table paths when split_rows_by and analysis are used on the same variable across analyses. Updated DESCRIPTION to reference a remote package source, aligning packaging with the new dependency strategy. This clarifies outputs for analysts, reduces ambiguity in complex analyses, and simplifies deployment with remote dependencies. Commit 4f90e36257768cac32d5985635250662730a97ae accompanies these changes.

Mar 1, 2025Performance summary for 2025-03 focusing on key accomplishments in insightsengineering/tern. Delivered two major features centered on compatibility and dependency hygiene, with measurable business impact through reduced upgrade risk and improved tooling coverage. Key features delivered: - Compatibility Update for R 4.4.0 and survival 3.8-3: raised minimum R version to 4.4.0 and updated survival package dependency to 3.8-3 to maintain compatibility with newer R releases and survival features. Coxph test skipped due to breaking changes in survival 3.8-3 to preserve overall test stability. (Commit: d8af02c8bca18d34834512c6d4e50fc1f8bf6d19) - Revdep dependency checks expanded to include new repositories: updated .revdeprefs.yaml to enable dependency checks/tooling for additional repositories, expanding coverage for dependency hygiene. (Commit: f3ccedb3e0a16d686fc8d23bd1c3c30ddf274ffa) Major bugs fixed: - No defects closed this month. Focus remained on proactive compatibility and dependency management rather than bug fixes. Overall impact and accomplishments: - Strengthened readiness for modern R environments, reducing upgrade risk for downstream users and CI pipelines. - Expanded dependency tooling coverage across more repositories, improving maintainability and reliability of the package ecosystem. - Set a foundation for smoother future upgrades and more robust test coverage in evolving R packages. Technologies/skills demonstrated: - R ecosystem management (version pins, survival package awareness) - Dependency management and RevDep tooling/workflow updates - YAML configuration updates (revdep testing index) and test strategy adjustments - Cross-repo coordination and change traceability via commit history
