You might need to
    export  http_proxy
before you start R.  (Perhaps this is obvious, but I say it just to be 
sure.) Once R is started try
    Sys.getenv("http_proxy")
to make sure the R process sees it.  Other than that, you might try  
method wget, and then you can test that wget works completely outside of 
R.  One more remote possibility is that you also need ssl_proxy set (and 
exported) since some paranoid systems apparently require ssl on 
connections to the http proxy (or something strange like that).
