packageStatus {utils}R Documentation

Package Management Tools

Description

Summarize information about installed packages and packages available at various repositories, and automatically upgrade outdated packages. These tools will replace update.packages and friends in the future and are currently work in progress.

Usage

packageStatus(lib.loc = NULL,
              repositories = getOption("repositories")())

## S3 method for class 'packageStatus':
summary(object, ...)

## S3 method for class 'packageStatus':
update(object, lib.loc = levels(object$inst$LibPath),
       repositories = levels(object$avail$Repository), ...)

## S3 method for class 'packageStatus':
upgrade(object, ask = TRUE, ...)

Arguments

lib.loc a character vector describing the location of R library trees to search through, or NULL. The default value of NULL corresponds to all libraries currently known.
repositories a character vector of URLs describing the location of R package repositories on the Internet or on the local machine.
object an object of class "packageStatus" as returned by packageStatus.
ask if TRUE, the user is prompted which packages should be upgraded and which not.
... currently not used.

Details

There are print and summary methods for the "packageStatus" objects: the print method gives a brief tabular summary and the summary method prints the results.

The update method updates the "packageStatus" object. The upgrade method is similar to update.packages: it offers to install the current versions of those packages which are not currently up-to-date.

Value

An object of class "packageStatus". This is a list with two components

inst a data frame with columns "Package", "Version", "Priority", "Bundle", "Depends", "Built", "Status" and "LibPath".
avail a data frame with columns "Package", "Version", "Priority", "Bundle", "Depends", "Built", "Status" and "Repository" (the URL of the directory from which they can be fetched).


These have similar content to the matrices returned by installed.packages and CRAN.packages.
