List of packages that need an update

Question

How can I produce a list of packages that need an update, i.e. a table with package name, version currently installed and version available at the repository?

I have tried to hack packageStatus(), installed.packages(), update.packages() but I am not able to force these functions to produce the desired output.

Note that I don't want to actually update these packages; I just want to see the mentioned list.

Take a look at old.packages(). on my system I have:

R> old.packages()
