But please follow the posting guide and give the 'at a minimum' 
information required as this area does depend on the OS. I will guess 
(you did not say) this is not Windows.

Be aware what the posting guide says about doing your own homework. The 
help for install.packages says

      See ‘download.file’ for how to handle proxies and other options to
      monitor file transfers.

and the referenced help file may well answer your question.
