use_package {usethis}

Depend on another package

Description

use_package() adds a CRAN package dependency to DESCRIPTION and offers a little advice about how to best use it. use_dev_package() adds a dependency on an in-development package, adding the dev repo to Remotes so it will be automatically installed from the correct location. There is no helper to remove a dependency: to do that, simply remove that package from your DESCRIPTION file.

use_package() exists to support a couple of common maneuvers:

• Add a dependency to Imports or Suggests or LinkingTo.

• Add a minimum version to a dependency.

• Specify the minimum supported version for R.

use_package() probably works for slightly more exotic modifications, but at some point, you should edit DESCRIPTION yourself by hand. There is no intention to account for all possible edge cases.

Usage

use_package(package, type = "Imports", min_version = NULL)

use_dev_package(package, type = "Imports", remote = NULL)

Arguments

package

Name of package to depend on.

type

Type of dependency: must be one of "Imports", "Depends", "Suggests", "Enhances", or "LinkingTo" (or unique abbreviation). Matching is case insensitive.

min_version

Optionally, supply a minimum version for the package. Set to TRUE to use the currently installed version or use a version string suitable for numeric_version(), such as "2.5.0".

remote

By default, an OWNER/REPO GitHub remote is inserted. Optionally, you can supply a character string to specify the remote, e.g. "gitlab::jimhester/covr", using any syntax supported by the remotes package.
