Interactive Dependency Diplomat (Base R Edition)

Source: R/audit_dependencies.R
audit_dependencies.Rd

Scans package source code for external package calls and cross-references them against the `DESCRIPTION` file to interactively resolve missing, unused, or misclassified dependencies without requiring any external tools.

Usage

audit_dependencies()

Value

Invisibly returns a named list with components: status ("done", "clean", or "error"), ghost_deps, bloat_deps, misclassified, and description_modified (logical).

Details

The function implements a zero-dependency approach to dependency auditing:

  1. Parses the `DESCRIPTION` file to identify currently declared `Imports` and `Suggests`.

  2. Recursively scans the `R/`, `tests/`, and `vignettes/` directories for `::` calls, `library()` calls, and `require()` calls.

  3. Filters out base R packages.

  4. Interactively prompts the user to add missing dependencies or remove unused ones from the `DESCRIPTION` file.

Warning

This function modifies files on disk or the global environment. Please ensure you have a backup or are using version control (e.g., Git) before execution.

Examples

if (interactive()) {
  audit_dependencies()
}
