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method installs outdated or missing packages from CRAN.
local_package_deps
extracts dependencies from a
local DESCRIPTION file.
dev_package_deps
lists the status of the dependencies
of a local package.
package_deps(packages, dependencies = NA, repos = getOption("repos"),
type = getOption("pkgType"))local_package_deps(pkgdir = ".", dependencies = NA)
dev_package_deps(pkgdir = ".", dependencies = NA,
repos = getOption("repos"), type = getOption("pkgType"))
# S3 method for package_deps
update(object, ..., quiet = FALSE, upgrade = TRUE)
A character vector of package names.
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).
A character vector giving repositories to use.
Type of package to update
. If "both", will switch
automatically to "binary" to avoid interactive prompts during package
installation.
path to a package directory, or to a package tarball.
A package_deps
object.
Additional arguments passed to install_packages
.
If TRUE
, suppress output.
If TRUE
, also upgrade any of out date dependencies.
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. |
