Package Dependency Resolution, Downloads and Installation

pkgdepends is a toolkit for package dependencies, downloads andinstallations, to be used in other packages. If you are looking for apackage manager, seepak.

• Look up package dependencies recursively.
• Visualize package dependencies.
• Download packages and their dependencies.
• Install downloaded packages.
• Includes a dependency solver to find a consistent set of dependencies.
• Supports CRAN and Bioconductor packages automatically.
• Supports packages on GitHub and GitLab.
• Supports packages in git repositories.
• Supports package bundles or files on the web.
• Supports local package file and trees.
• Supports theRemotes entry in theDESCRIPTION file.
• Caches metadata and downloaded packages viapkgcache
• Performs all downloads and HTTP queries concurrently.
• Builds and installs packages in parallel.

Install the package with:

install.packages("pkgdepends")

If you need the development version, install it with

pak::pak("r-lib/pkgdepends")

library(pkgdepends)

A package reference (ref) specifies a location from which an R packagecan be obtained from. Examples:

devtoolscran::devtoolsbioc::Biobaser-lib/pkgdependshttps://github.com/r-lib/pkgdependslocal::~/works/shiny

See“Packagereferences”for details.

Dependencies of the development version of the cli package:

pd<- new_pkg_deps("r-lib/pkgcache")pd$solve()pd$draw()

See thepkg_depsclass for details.

Downloading all dependencies of a package:

pdl<- new_pkg_download_proposal("r-lib/cli")pdl$resolve()pdl$download()

See thepkg_download_proposalclass for details.

Installing or updating a set of package:

lib<- tempfile()dir.create(lib)pdi<- new_pkg_installation_proposal("r-lib/cli",config=list(library=lib))pdi$solve()pdi$download()pdi$install()

pkg_deps,pkg_download_proposalandpkg_installation_proposalall resolve their dependencies recursively, to obtain information aboutall packages needed for the specifiedpackagereferences.See“Dependencyresolution”for details.

The dependency solver takes the resolution information, and works outthe exact versions of each package that must be installed, such thatversion and other requirements are satisfied. See“The dependencysolver”for details.

pkg_installation_proposalcan create installation plans, and then also install them. It is alsopossible to import installation plans that were created by other tools.See“Installationplans”for details.

The details ofpkg_deps,pkg_download_proposalandpkg_installation_proposalcan be tuned with a list of configuration options. See“Configuration”for details.
