[R] Package installed, functional but not available

[Prof Brian Ripley]

If you read the help page it says

Description:

      Summarize information about installed packages and packages
      available at various repositories, and automatically upgrade
      outdated packages.
...
    avail: a data frame with columns as the _matrix_ returned by
           'available.packages' plus '"Status"', a factor with levels
           'c("installed", "not installed", "unavailable")'..

so this is 'available' as in 'available.packages' (qv).

No, not on the repositories you specified.
