You read incorrectly: install.packages() works with local files, but 
to *update* you need to use a repository (which can be on your disc, 
but needs to have a PACKAGES or PACKAGES.gz file).

      The main function of the set is ‘update.packages’.  First a list
      of all packages/bundles found in ‘lib.loc’ is created and compared
      with those available at the repositories. ...
