step_install_pkg: Step: Install packages

Description

These steps are useful if your CI run needs additional packages. Usually they are declared as dependencies in your DESCRIPTION, but it is also possible to install dependencies manually. By default, binary versions of packages are installed if possible, even if the CRAN version is ahead.

A step_install_deps() step installs all package dependencies declared in DESCRIPTION, using remotes::install_deps(). This includes upgrading outdated packages.

A step_install_cran() step installs one package from CRAN via install.packages(), but only if it's not already installed.

A step_install_github() step installs one or more packages from GitHub via remotes::install_github(), the packages are only installed if their GitHub version is different from the locally installed version.

Usage

step_install_deps(repos = repo_default(), type = NULL)
step_install_cran(package = NULL, ..., repos = repo_default(), type = NULL)
step_install_github(repo = NULL, ..., type = NULL)

Arguments

repos

CRAN-like repositories to install from, defaults to repo_default().

type

Passed on to install.packages(). The default avoids installation from source on Windows and macOS by passing .Platform$pkgType.

package

Package(s) to install

...

Passed on to install.packages() or remotes::install_github().

repo
