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information about installed packages and packages available at various repositories, and automatically upgrade outdated packages.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

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")).
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
