Only if the so-called repository contains (only) binary builds under R 
2.2.x of packages for Windows.

It would be better to set up the 'repository' correctly as a repository. 
See my article in R-news 5/1 and the R-admin manual for the format of a 
repository.

Are these source packages or binary packages or what?

Your syntax is incorrect here: Peter has silently corrected it.
file:// syntax has an element for 'machine' followed by a third slash
(although 'machine' is not supported in R, so it should be empty).
