What does 'update' mean here?  Do you want to install those, or install 
later versions from CRAN, or what?

update.packages() is about updating from a repository, which you do not 
have, AFAICS.

I presume all your paths are missing a leading / ?

You can state it, but it cannot be fulfilled. It would be lib.loc=.Library 
or lib.loc="/usr/local/lib/R/library/"

Probably not, as you need to give a library tree to install into, one with 
suitable permissions.  To give a real example,

                  lib="~/R/library", repos=NULL)
