Character vector of packages to update. If NULL all
installed packages are updated.
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package_deps to see which packages are out of date/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.
