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 pak::local_install_dev_deps().
This includes upgrading outdated packages.
This step can only be used if a DESCRIPTION file is present in the repository root.
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 pak::pkg_install(), the packages are only installed if their
GitHub version is different from the locally installed version.
Usage
step_install_deps(dependencies = TRUE)
step_install_cran(package = NULL, ...)
step_install_github(repo = NULL, ...)Arguments
- 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.
- package
Package(s) to install
- ...
Passed on to
pak::pkg_install().- repo
Package to install in the "user/repo" format.
