devtools (version 1.11.1)

package_deps: Find all dependencies of a CRAN or dev package.

Description

Find all the dependencies of a package and determine whether they are ahead or behind CRAN. A print() method identifies mismatches (if any) between local and CRAN versions of each dependent package; an update() method installs outdated or missing packages from CRAN.

Usage

package_deps(pkg, dependencies = NA, repos = getOption("repos"),
  type = getOption("pkgType"))
dev_package_deps(pkg = ".", dependencies = NA, repos = getOption("repos"),
  type = getOption("pkgType"), force_deps = FALSE, quiet = FALSE)
## S3 method for class 'package_deps':
update(object, ..., quiet = FALSE, upgrade = TRUE)

Arguments

pkg

A character vector of package names. If missing, defaults to the name of the package in the current directory.

dependencies

Which dependencies do you want to check? Can be a character vector (selecting from "Depends", "Imports", "LinkingTo", "Suggests", or "Enhances"), or a logical vector.

TRUE is shorthand for "Depends", "Imports", "LinkingTo" and "Sugg

repos

A character vector giving repositories to use.

type

Type of package to update. If "both", will switch automatically to "binary" to avoid interactive prompts during package installation.

force_deps

whether to force installation of dependencies even if their SHA1 reference hasn't changed from the currently installed version.

quiet

If TRUE, suppress output.

object

A package_deps object.

...

Additional arguments passed to install_packages.

upgrade

If TRUE, also upgrade any of out date dependencies.

Value

• A data.frame with columns:

  ll{ package The dependent package's name, installed The currently installed version, available The version available on CRAN, diff An integer denoting whether the locally installed version of the package is newer (1), the same (0) or older (-1) than the version currently available on CRAN. }

Examples

package_deps("devtools")
# Use update to update any out-of-date dependencies
update(package_deps("devtools"))
