Could somebody please assist with the problem I have now.
At our university certain changes have been made to users regarding accessing the internet.
I have re-installed the (current) version of R, using custom settings (for Windows XP), choosing amongst other things "Internet2" somewhere.
Now, when I wish to install new packages, I first have to select a CRAN mirror.
R gives me a list to choose a mirror. But after choosing the mirror, R comes back with the following:

R> chooseCRANmirror()
Warning message:
In open.connection(con, "r") :
  cannot open: HTTP status was '407 Proxy Authentication Required'

I need to tell R that I need a proxy server, and give my proxy settings (how I log onto the server to connect to the Internet.

My question is: Where/how do I set this?

Any advice is much appreciated.

Thank you.
