The http_proxy environmental variable should look something like:
http://your.proxy.com:8080 (at least that is what mine looks like and it
works), my http_proxy_user is just the word "ask" which makes it
prompt me for my username and password (first time I connect each session).
You can double check that R is getting the correct values by using:
Sys.getenv("http_proxy") and seeing that that matches what it should.
I have not received your particular error, so am not sure exactly what is
causing it. Try the above, it may help.
