A Fresh Approach to R Package Installation
Install the package from CRAN:
(After installation, you might also want to run
pak::pak_setup(); it’ll be run automatically when needed but you might want to do it now to save some time later.)
pkg_install() to install CRAN or Bioconductor packages:
To install GitHub packages, use the
All dependencies will be installed as well, to the same library.
Fast downloads and HTTP queries. pak performs all HTTP requests concurrently.
Fast installs. pak builds and installs packages concurrently.
Metadata and package cache. pak caches package metadata and all downloaded packages locally. It does not download the same package files over and over again.
Lazy installation. pak only installs the packages that are really necessary for the installation. If the requested package and its dependencies are already installed, pak does nothing.
Private library (pak’s own package dependencies do not affect your regular package libraries and vice versa).
Every pak operation runs in a sub-process, and the packages are loaded from the private library. pak avoids loading packages from your regular package libraries. (These package files would be locked on some systems, and locked packages cannot be updated. pak does not load any package in the main process, except for pak itself).
To avoid updating locked packages, pak warns and requests confirmation for loaded packages.
Dependency solver. pak makes sure that you end up in a consistent, working state of dependencies. If finds conflicts up front, before attempting installation.
BioC packages. pak supports Bioconductor packages out of the box. It uses the Bioconductor version that is appropriate for your R version.
GitHub packages. pak supports GitHub packages out of the box. It also supports the
Remotes entry in
DESCRIPTION files, so that GitHub dependencies of GitHub packages will also get installed. See e.g. https://cran.r-project.org/package=remotes/vignettes/dependencies.html
Package sizes. For CRAN packages pak shows the total sizes of packages it needs to download.
