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

components
inst |
a data frame with columns
