Package Management Tools

Description

Summarize information about installed packages and packages available at various repositories, and automatically upgrade outdated packages.

Usage

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

## 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.
`method`	Download method, see `download.file`.
`type`	type of package distribution: see `install.packages`.
`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

The URLs in repositories should be full paths to the appropriate contrib sections of the repositories. The default is contrib.url(getOption("repos")).

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 as the matrix returned by `installed.packages` plus `"Status"`, a factor with levels `c("ok", "upgrade")`. Only the newest version of each package is reported, in the first repository in which it appears.
`avail`	a data frame with columns as the matrix returned by `available.packages` plus `"Status"`, a factor with levels `c("installed", "not installed", "unavailable")`..

For the summary method the result is also of class "summary.packageStatus" with additional components

`Libs`	a list with one element for each library
`Repos`	a list with one element for each repository

with the elements being lists of character vectors of package name for each status.

Examples

## Not run: 
x <- packageStatus()
print(x)
summary(x)
