packageStatus {utils} | R Documentation |
Summarize information about installed packages and packages available at various repositories, and automatically upgrade outdated packages.
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, ...)
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. |
The URLs in repositories
should be full paths to the
appropriate contrib sections of the repositories. The default is
contrib.url(getOption("repos"))
. (Prior to R 2.1.0 this was
hardcoded as the CRAN and Bioconductor repositories.)
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.
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") ..

installed.packages
, available.packages
