R: Find all dependencies of a CRAN or dev package.
package_deps
R Documentation
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update() method installs outdated or missing packages from CRAN.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"))
## 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
"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.
Examples
## Not run:
package_deps("devtools")
# Use update to update any out-of-date dependencies
