devtools (version 1.12.0)

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identifies mismatches (if any) between local and CRAN versions of each dependent package; an update() method installs outdated or missing packages from CRAN.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"))
"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 "Suggests". NA is shorthand for "Depends", "Imports" and "LinkingTo" and is the default. FALSE is shorthand for no dependencies (i.e. just check this package, not its dependencies).

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.
object
A package_deps object.
...
Additional arguments passed to install_packages.
quiet
If TRUE, suppress output.
upgrade
If TRUE, also upgrade any of out date dependencies.

Value

A data.frame with columns:
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.
