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method installs outdated or missing packages from CRAN.
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, dependencies = NA,
upgrade = c("ask", "always", "never"), force = FALSE,
quiet = FALSE, build = TRUE, build_opts = c("--no-resave-data",
"--no-manual", "--no-build-vignettes"), repos = getOption("repos"),
type = getOption("pkgType"), ...)
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
.
path to a package directory, or to a package tarball.
Additional arguments passed to install_packages
.
A package_deps
object.
One of "ask", "always" or "never". "ask" prompts the user for
which out of date packages to upgrade. For non-interactive sessions "ask" is
equivalent to "always". TRUE
and FALSE
are also accepted and
correspond to "always" and "never" respectively.
Force installation, even if the remote state has not changed since the previous install.
If TRUE
, suppress output.
If TRUE
build the package before installing.
Options to pass to R CMD build
, only used when build
is TRUE
.
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. |
