[R] internet proxy settings (win)

Mon Mar 10 12:56:37 CET 2008

I cannot access internet through R.
My IT-guys told me that I should set the proxy and the port and then
everything will be fine. Where can I set them?
I use R 2.6.2 under Windows 2000 and these settings are those of the
Internet Explorer (no password).

I read http://cran.at.r-project.org/bin/windows/base/rw-FAQ.html#The-Internet-download-functions-fail_002e
but staring R by
"C:\Program Files\R\R-2.6.2\bin\Rgui.exe" --internet2
a package update still gives me an error:

> update.packages(ask='graphics')
--- Please select a CRAN mirror for use in this session ---
Fehler: Indizierung außerhalb der Grenzen
Zusätzlich: Warning messages:

2: In read.dcf(file = tmpf) : Line starting '   <head> ...' is malformed!
3: In read.dcf(file = tmpf) : Line starting '</html> ...' is malformed!

Do you know what I could try next?
Thanks
