devtools (version 1.13.3)

update_packages: Update packages that are missing or out-of-date.

Description

Works similarly to install.packages() but doesn't install packages that are already installed, and also upgrades out dated dependencies.

Usage

update_packages(pkgs = NULL, dependencies = NA,
  repos = getOption("repos"), type = getOption("pkgType"))

Arguments

pkgs

Character vector of packages to update. IF TRUE all installed packages are updated. If NULL user is prompted to confirm update of all installed packages.

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.

See Also

package_deps to see which packages are out of date/ missing.

Examples

# NOT RUN {
update_packages("ggplot2")
update_packages(c("plyr", "ggplot2"))
# }
