local_install_dev_deps: Install all (development) dependencies of a package tree

In pak: Another Approach to Package Installation

Install all (development) dependencies of a package tree

Description

Installs all dependencies of a package tree (or source package file), without installing the package tree itself. It installs the development dependencies as well, specified in the Suggests field of DESCRIPTION.

Usage

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

Arguments

root	Path to the package tree.
lib	Character vector of library paths to consider when creating the installation plan. The first library path is the target where packages will be installed. Additional library paths, if provided, are visible to the solver as candidates for satisfying dependency requirements. If a needed package is found here at an acceptable version, it won't be re-installed in lib[1]. Base and recommended packages in .Library are always considered, i.e. a recommended package is only duplicated in lib[1] if a newer version is required.
upgrade	When FALSE, the default, pak does the minimum amount of work to give you the latest version(s) of pkg. It will only upgrade dependent packages if pkg, or one of their dependencies explicitly require a higher version than what you currently have. It will also prefer a binary package over to source package, even if the binary package is older. When upgrade = TRUE, pak will ensure that you have the latest version(s) of pkg and all their dependencies.
ask	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.
dependencies	What kinds of dependencies to install. Most commonly one of the following values: NA: only required (hard) dependencies, TRUE: required dependencies plus optional and development dependencies, FALSE: do not install any dependencies. (You might end up with a non-working package, and/or the installation might fail.) See Package dependency types for other possible values and more information about package dependencies.
