devtools (version 1.13.3)

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identifies mismatches (if any) between local and CRAN versions of each dependent package; an update() method installs outdated or missing packages from CRAN.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"), bioconductor = TRUE)
# S3 method for 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 "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.

bioconductor

Install Bioconductor dependencies if the package has a BiocViews field in the DESCRIPTION.

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.

Examples

# NOT RUN {
package_deps("devtools")
# Use update to update any out-of-date dependencies
update(package_deps("devtools"))
# }
