Under windows, that problem sometimes goes away if you install R using the 'use Internet2' option or, _before attempting any connections_, you use setInternet2() If that does not work you will need to contact your local network administrator to permit access to the repositories. In our case that was a bit of a faff because we had to log the http request (that is, the raw http request, not the url) and then update (remote) proxies to recognise the structure of a CRAN repository request as an allowed site. Organisations are increasingly using such off-site 'site filtering', so it's become more of a problem. It may help you or your administrator to try simply reading direct from the URL, for example with readLines(url("http://cran.ms.unimelb.edu.au/")) If your internet connection is working, that should return html lines (I see 24 lines at that url, today) containing the html header and the <frameset> for a CRAN front page. But if your proxy or firewall are returning an error the text returned can be informative as to where the problem is. Failing all that, you could download the zip or tar.gz from CRAN) and install 'from a local zip file'.
