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 |

avail |

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.
