First public release.
check_packages() resolves the system packages an R
package needs on a given Linux platform. Four backends are available:
"auto" (default), "bundled",
"ppm", and "pak".check_library() audits installed packages in an R
library path.check_project() and
detect_project_packages() scan a project directory,
preferring renv.lock, then DESCRIPTION, then
source files.detect_platform() reads /etc/os-release on
Linux, sw_vers on macOS, and parses fixture files for
tests.detect_package_manager() returns the package manager
for a platform (apt, dnf, yum,
zypper, apk, brew).resolve_platform() accepts NULL, an
existing platform object, <distro>-<version>
shorthand, or a codename alias (jammy, noble,
resolute, bookworm, trixie).install_command() generates platform-appropriate
install commands.dockerfile() and
write_dockerfile_snippet() produce Dockerfile
snippets.github_actions() (alias gha()) produces a
GitHub Actions YAML step.admin_request() drafts a plain-text request for system
administrators.write_install_script() writes a POSIX shell
script.write_report() and write_json() persist a
plan to disk.as_install_plan() returns a structured list suitable
for downstream tooling.diagnose_log() (alias
diagnose_install_log()) matches common compiler and linker
error patterns and resolves failed package names back to system
requirements.check_error() is a convenience wrapper that reads
geterrmessage().diagnose_failed_packages() resolves a known list of
failed R packages.ppm_platforms(), check_ppm(),
ppm_repo(), ppm_sysreqs(), and
use_ppm() integrate with the Posit Package Manager API and
binary repository URLs.setup_advice() produces a practical, beginner-friendly
Linux setup checklist with optional shell-script output.explain() prints a friendly per-package
explanation.default-libmysqlclient-dev (was
libmysqlclient-dev, which does not exist on Debian),
libgsl-dev (was libgsl0-dev), and
libfreetype-dev (was libfreetype6-dev).detect_project_packages() now detects
requireNamespace() calls and ignores package names that
appear only in line comments.setup_advice() generates Debian repository setup using
the modern deb822 Signed-By keyring format (matching CRAN’s
current Debian instructions), drops a no-op Fedora
repoquery line, and presents the Fedora COPR step as
optional.ppm_repo() and check_ppm() work for them.sysreqr has zero required
dependencies: no Imports, no Depends
beyond base R. The Suggests field lists
testthat, knitr, rmarkdown, and
withr, used only for tests and vignette building; none of
them are loaded at run time.pak::pkg_sysreqs(), both of which are detected at run
time and never required.backend = "ppm" or backend = "pak" when
newer live metadata is needed.These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
