[R] have difficulty in installing packages

[Prof Brian Ripley]

You seem to be using Windows.  I do suggest you ask local advice, as the 
problem is almost certainly local your site.

You may need to set a proxy -- see the rw-FAQ.
You may need to set a policy to allow R through a firewall.
You may need permission to download at all, and indeed the trouble you are 
having with your unnamed browser suggests so.
