Manifest-Based Dependency Conflict Detection for Sandboxed R Sessions R package depguard version 0.1.0 Provides lightweight, manifest-based checking of R package dependencies (including transitive dependencies) against the currently installed environment, without requiring a full project lockfile. Designed for sandboxed or ephemeral notebook environments (e.g. Kaggle, Colab, Binder) where 'renv'-style lockfile ownership is impractical. Includes session snapshot/diff tools (building on 'sessioninfo') to detect when an install silently changes the version of a package that is already loaded, and optional single-package version rollback. Software Depends: R (>= 3.5) Imports: tools, utils, sessioninfo, cli Suggests: remotes, pak, testthat (>= 3.0.0), knitr, rmarkdown, spelling Samruddhi Amol Shah <samruddhi.bitnbyte@gmail.com> Comprehensive R Archive Network (CRAN) Samruddhi Amol Shah [aut, cre], Kartik Patel [aut], Amrit Pal [ctb] MIT + file LICENSE (https://CRAN.R-project.org/package=depguard/LICENSE) 2026-09-24 application/tgz https://CRAN.R-project.org/package=depguard doi:10.32614/CRAN.package.depguard
