Installs the hard dependencies of a package tree (or source package file), without installing the package tree itself.


  root = ".",
  lib = .libPaths()[1],
  upgrade = TRUE,
  ask = interactive(),
  dependencies = NA



Path to the package tree.


Package library to install the packages to. Note that all dependent packages will the be installed here, even if they are already installed in another library.


When FALSE, the default, does the minimum amount of work to give you the latest version of pkg. It will only upgrade packages if pkg, or one of its dependencies, explicitly requires a higher version than what you currently have.

When upgrade = TRUE, will do ensure that you have the latest version of pkg and all its dependencies.


Whether to ask for confirmation when installing a different version of a package that is already installed. Installations that only add new packages never require confirmation.


Dependency types. See pkgdepends::as_pkg_dependencies() for possible values. Note that changing this argument from the default might result an installation failure, e.g. if you set it to FALSE, packages might not build if their dependencies are not already installed.


Data frame, with information about the installed package(s).


Note that development (and optional) dependencies, under Suggests in DESCRIPTION, are not installed. If you want to install them as well, use local_install_dev_deps().
